Is it OK to continue feeding my fish summer food and just feed them less? | Decorative Ponds & Water Gardens Q & A

Q: Is it OK to continue feeding my fish summer food and just feed them less?

Q: Is it OK to continue feeding my fish summer food and just feed them less?

Don – Livingston, TN

A: Koi have temperamental digestive systems. To stay healthy and happy, they need specific types of food at different times of year—so no, we don’t recommend feeding your fish summer food as we go into fall. Here’s why.

Feeding Less

Giving your fish less food is a good idea; especially as water temperatures start to drop. This will cause them to produce less waste, which will help in maintaining good water quality, and slow down their digestive systems. Fish naturally do this on their own; they will eat less food as temperatures decrease because the cooler water will slow their metabolism.

Macronutrient Shift

As water temperatures cool, fish need a diet that’s easier for them to digest—a wheat germ-based diet like our Spring and Fall Fish Food—that’s carbohydrate-heavy rather than protein-rich. We recommend using a wheat germ based food when water temperatures are between 40 to 50 degrees Fahrenheit. In the summer, fish crave protein to grow and put on muscle weight. But in the fall and spring, they’re in transition between fasting and feasting and lacking some digestive enzymes, so they’ll need something that’ll gently slow down (or wake up) their metabolism.

Up the Veggies

Even though wheat germ is the most common food to feed fish in the fall, you can still give your finned pals a treat in place of high-protein foods, too. Toss them some Cheerios, oatmeal or brown rice. Share some healthy vegetables, like carrots, pumpkin or frozen peas. They’ll provide important nutrients while being gentle on their system.

40-Degree Mark

As soon as water temperatures consistently read below 40 degrees Fahrenheit on your pond thermometer, remember to stop feeding your fish for the winter. Don’t worry: They won’t starve. The fast will give your fish the opportunity to give its digestive system a break and live off its fat reserves it added in the summer. In the spring, they’ll clean up and look fresher and healthier than ever.

I started off with 4-inch koi and now they’re 8 inches. How big will they get before they stop growing? | Decorative Ponds & Water Gardens Q & A

Q: I started off with 4-inch koi and now they’re 8 inches. How big will they get before they stop growing?

Lauren – Lincoln, NE

A: In an ideal environment—a supersize space with pristine water conditions at a stable 75 degrees Fahrenheit—an adult koi can reach a whopping 3 feet long. A yard! Nearly a full meter! Yep, that’s a really big fish.

Don’t worry: Chances are slim that your finned pal will grow to that immense length, but you can help it reach its full potential. Koi will keep growing and growing throughout their lives, sometimes faster than others. How fast and large they grow depend on several factors, including:

  • Water quality. Clean water pumped full of oxygen will promote a fish’s health and growth, while poor water quality can stunt its growth. Koi will tolerate a dirty, cloudy environment, but their development and vitality will suffer. Make sure you have an aeration kit in place and are using beneficial bacteria from the DefensePAC® to keep the water crystal clear.
  • Water temperature. A steady 75° F will keep koi in a more active growth state where they’re building muscle and body mass like crazy. Cooler or fluctuating water temperatures trigger a slower growth rate as they slow down their metabolism and activity level. If you live anywhere other than in the tropics, expect to see slower growth in the winter months.
  • Nutrition. Food—and how much of it they eat—matters. Fish food that’s packed with protein and vitamins is formulated to help koi grow and develop. Some also contain ingredients that boost your fish’s vibrant colors.
  • Genetics. Genes play a huge role in how large a koi could grow in the right conditions. Colossal parents often produce colossal offspring, and if those fry live in a spacious pond with clean, aerated water and good food, who knows how big they’ll get!
  • Age. Like most living things, koi develop faster when they’re young and slower as they age. Your 4-inch koi quickly doubled in size because they’re still adolescents; as they get older, their growth rate will slow down.

If you have big plans for your koi, give them an ideal ecosystem and good grub. Your colorful friends may not reach that 3- or 4-foot mark—but you never know!

What can I do to help out a fish that was attacked by a heron? | Decorative Ponds & Water Gardens Q & A

Q: What can I do to help out a fish that was attacked by a heron?

Q: What can I do to help out a fish that was attacked by a heron?

Lori – Glen Forney, PA

A: Ouch. A heron attack isn’t pretty – and it’s potentially deadly to your fish. Unfortunately, you can’t call 9-1-1 or an emergency fish veterinarian for a pond call, but you can try some things that could save your pet’s life.

 

  1. Examine, Triage: The first thing to do is examine the victim and do some triage. Capture the injured fish in a pond net and take a closer look at its wounds without removing it from the water. How severe is the injury? Are there just a few scrapes, or does the fish have an open wound?
  2. Minimal Injuries: If your fish’s injuries aren’t too severe and it appears to be normal except for a few scrapes, leave it in the pond and add some Stress Reducer PLUS to the water. The liquid formula will help to calm the fish and rebuild its slime coat, which defends it against infection. You might also want to add some soothing salt to the water (read about it here).
  3. Remove and Isolate: If your fish is severely injured, set up a quarantine tank with pond water and an aerator, add some Stress Reducer PLUS, put it in a shaded and protected area, and gently move the fish from the pond to the tank.
  4. Watch for Infection: Keep an eye on your fish while it’s in the quarantine tank. Because damaged tissue becomes a breeding ground for bacterial and fungal pathogens, watch for signs of infection. If you see split or ragged fins, slimy patches or red ulcers on its body, or any other unusual symptoms, use CrystalClear® Wipeout™ or API® MelaFix to heal the wounds and restore damaged tissue.

While your finned friend is recovering, makes some plans for how you’ll guard your pond against future attacks. A Blue Heron Decoy will dissuade the real things from stopping by for a snack. Pond netting will prevent birds from reaching the water. Floating, submerged and marginal aquatic plants give your fish somewhere to hide, as do fish shelters, like the Koi Kastle. Set your fish up for safety – especially since that heron will be back for seconds!

My friend talks about her fish coming up to eat from her hand. How can I get my fish to do the same? | Decorative Ponds & Water Gardens Q & A

Q: My friend talks about her fish coming up to eat from her hand. How can I get my fish to do the same?

Q: My friend talks about her fish coming up to eat from her hand. How can I get my fish to do the same?

Donna – Chesterfield, MO

A: Talk about a cool party trick! Feeding by hand is not only a fun way to show your friends how well-trained your fish are, but it also gives you an opportunity to bond with your finned pals.

Teaching your fish how to eat from your hand starts with understanding the temperament of the fish themselves. Are your fish friendly? Do they swim up and say “Glub, glub, hi!” when you visit your pond? Or do they scatter when you approach and your shadow falls on the water?

Friendly fish are easier to train. They already associate you as an approachable face that brings them tasty food every day. Sketchy fish, however, can be more of a challenge. They might be newbies that don’t recognize you or your feeding routine, or they might be spooked from predators visiting your pond.

If you’ve ruled out the possibility of predators (or put up some predator-control measures), follow these steps to help teach your fish to eat from the palm of your hand:

  1. Set a Routine: Fish are creatures of habit. They’re more likely to respond to something that happens the same way every day (or frequently, at least). To set a mealtime routine, visit your pond at the same location, at the same time of day, on a regular basis. They’ll get to know your patterns and learn to recognize you – and feeding time.
  2. Make Them Work: Throwing a handful of Growth & Vibrance Fish Food into the water and walking away teaches your fish an easy snatch-and-run feeding style. Instead, toss them a few pellets at a time and wait for the fish to eat them. They’ll rush to get the food first! Even the shy koi will get in on the action. This toss-and-wait style reminds them that you are hanging out and something exciting is happening.
  3. Get Brave – and Get Wet: Once your fish are used to your feeding routine and race to the pond’s edge to greet you, take the plunge! Hold a few pellets loosely in your hand just at the water surface without making any sudden or quick movements. It takes only one fish to act bravely and let the others know it’ll be OK. Before you know it, they’ll be racing to your hand to be fed!

Once your fish are trained to eat from your hand, you’ll be tempted to keep offering them food. Prevent overfeeding them by measuring out a predetermined amount of food – and stop when it’s all gone. If you can’t help yourself (or you’re sharing this cool new party trick with your friends), at least be sure to have some natural bacteria, like Nature’s Defense®, on hand to help clean up the leftovers after dinner.

The pH level in my pond always reads high. What can I do to reduce it? | Decorative Ponds & Water Gardens Q & A

Q: The pH level in my pond always reads high. What can I do to reduce it?

Q: The pH level in my pond always reads high. What can I do to reduce it?

Mike – Forest Hills, NY

A: Your pond’s pH – or potential hydrogen – level is an important measurement to understand because it affects the health of those things swimming around in the water. If your pH level is too high or too low, it could affect your fishes’ ability to reproduce, fight disease and metabolize food. It can also impact the well-being of other living things in your pond, like plants, amphibians and other aquatic critters.

A pH test, like the one found in the API® Pond Master Test Kit, can reveal a lot about your pond. But what does a high or low pH reading mean, and how can you adjust its level – or should you just leave it alone? Read on to learn more about understanding your pH level and how to change it.

Potential Hydrogen Defined

In super simple terms, pH is a measure of how acidic or alkaline a water body is on a scale from 0 to 14. Pure water is neutral. It has a pH close to 7.0 at 77 degrees F. Blood is also close to neutral. Ammonia’s pH is ~11, which is high on the alkaline charts, while stomach acid’s pH is ~1, which acidic enough to burn through your chewed-up chow.

Adjusting to a Proper pH

You don’t have to keep your pond at a perfect 7.0 pH all the time. In fact, an acceptable pH reading for a pond is 6.5 – 8.5, so if your score falls in this range you need not make any changes at all. If it’s outside those levels, however, you will need to make some adjustments. Here are some ways to reduce your pH:

  1. Partial Water Change: Replacing some of your pond water with fresh water is one way to reduce your pH. Remember to treat with water with a conditioner, like The Pond Guy® Stress Reducer PLUS, to remove impurities and heavy metals that could be harmful to your fish.
  2. Use pH Reducer: If you need to adjust your pH using a pH stabilizer like pH Lift or pH Drop, apply enough treatment to shift the levels 0.5 at a time, wait several hours before re-treating, and test the waters often with your API® Pond Master Test Kit.
  3. Test Your Water: Try testing your tap water, especially if you’re on a well. If the pH is high from your well, then your pond will stay at about that level and you won’t be able to do much to treat it.
  4. Try Clarity Defense®: A water clarifier like Clarity Defense® can help to add trace minerals while buffering pH to promote stable levels and prevent swings. Plus, it clears cloudy water by locking up excess nutrients and allowing your filter to remove them.

Try these tricks to reduce the pH levels in your pond – but remember to do so very gradually. Good luck!

My fish are looking for food. Can I feed them now? What kind of food do I give them? | Decorative Ponds & Water Gardens Q & A

Q: My fish are looking for food. Can I feed them now? What kind of food do I give them?

Q: My fish are looking for food. Can I feed them now? What kind of food do I give them?

Rick – Great Falls, MT

A: Fish sure seem know when spring is on its way. This time of year, your koi and goldfish that have been hibernating over the winter are beginning to waking up. Your fish may be moving slow, but they’re hungry and looking for food.

Slow Eaters

When water temperatures dip below 40 degrees Fahrenheit in the winter months, your fishes’ metabolisms slows down. They enter into a hibernation-type state, during which time they require little or no food. They literally live off the fat stores in their body.

As the water temperature rises above 40 degrees in the spring, the fish start moving. Their metabolisms turn back on, and they need food to fuel their increased activity. To transition the fish from no food to daily food, fish experts recommend feeding a wheat germ-based diet when water temperatures are consistently between 40 and 50 degrees. A diet like The Pond Guy® Spring & Fall Fish Food is quickly and easily digested by the fish.

Summertime Bounty

In the warmer months when your water temperature tops 50 degrees, you can continue to feed the wheat germ-based diets, or you can choose to gradually re-introduce protein-based diets that help the fish grow quickly and show off their colors. Here’s what we recommend:

Choose the diet that best fits in with your goals for the fish. If you’re not interested in growing your Kohaku into show-quality specimens, for instance, stick to the everyday or color enhancement diet.

Word of Warning

The weather may be warming up, but make sure the water temperatures are at a consistent 40 degrees before you start feeding your fish. Feeding them before they’re able to properly digest the food can lead to health issues.

I’m tired of fighting algae. Will a UV take care of all the algae growth? | Decorative Ponds & Water Gardens Q & A

Q: I’m tired of fighting algae. Will a UV take care of all the algae growth?

Q: I’m tired of fighting algae. Will a UV take care of all the algae growth?

Beth – Casselberry, FL

A: Who isn’t tired of battling algae!

Caused by excess fish waste and dead organics from leaves or previous algae blooms combined with excessive sunlight, all that garish green growth looks horrible, ruins your water quality, and creates a headache for you and your fish.

Is an ultraviolet clarifier the answer? It depends on the type of algae you’re trying to destroy.

Know Your Algae

The algae that forms in your pond comes in two basic flavors: planktonic and filamentous.

  • Planktonic algae, the source of pea soup algae blooms, are floating, microscopic plants that color pond water shades of green, blue-green, brown or variations in between. In controlled amounts, this type of algae can actually be beneficial. It’s considered the start of the pond food chain as the tiny plants feed fish inhabitants, and it can also shade the pond’s bottom, preventing subsurface nuisance plants from growing. In uncontrolled amounts, however, planktonic algae can cause oxygen depletions and fish kill.
  • Filamentous (string) algae are single-celled plants that form long, visible chain, threads or filaments. These threads, which start growing along the bottom of the pond in shallow water or on rocks or other aquatic plants, intertwine and form mats that resemble wet wool. When these mats rise to the surface, they’re commonly referred to as pond scum. These mats make great homes for micro- and macro-invertebrates, like bugs and worms, but they’re also unsightly.

UV clarifiers work by destroying the ultrafine planktonic algae – but, unfortunately, they do nothing to combat the filamentous algae. You’ll need a different strategy for the stringy stuff.

Battling Planktonic Algae

So how does ultraviolet light fight planktonic algae? When the algae cells are exposed to the bulb’s ultraviolet rays, radiation destroys the plants’ cellular walls. As a result, the tiny particles of dead algae clump together, and those clumps are then removed by your mechanical filtration system.

For the UV clarifier to work properly, however, follow these guidelines:

  • Replace bulbs yearly. Worn-out bulbs – even if they still light up – may not be as effective at controlling green water.
  • Watch your flow rate. Pushing water past the UV too fast can damage the unit and not allow enough contact time with the UV bulb for it to be effective.
  • Don’t flow too slow. Running a UV at too slow of a flow will act as a sterilizer and may also have a negative affect on natural bacteria meant to help decompose dead organics and fish waste.

Finding Balance

If you have an algae problem, be it planktonic or filamentous, it indicates your pond is out of balance. An ultraviolet clarifier should actually be one of your last tactics! Add some beneficial bacteria from the DefensePAC® Pond Care Package to help reduce the amount of organics in your pond. Start aerating the water. Consider using pond dye. If you have a thriving fish population, think about finding a new home for them (but don’t release them into the wild!). Manage the nutrients, sunlight and oxygen levels, and your algae proliferation should naturally level out on its own.
