Is there any danger to my fish if the pond is always in direct sunlight? | Decorative Ponds & Water Gardens Q & A

Q: Is there any danger to my fish if the pond is always in direct sunlight?

A: Sunshine has its benefits – but it also has its dangers. Direct sunlight with no shade can raise the water temperature in your pond and reduce the levels of oxygen available to your fish. All those rays can also fuel algae blooms, as well as give your fish a sunburn (yes, really!).

Don’t worry: You don’t need to relocate your water feature to a less sunny locale. There are some easy ways to add shade to your pond, and here’s what we recommend.

  • Terrestrial Shade: Trees, and terrestrial and marginal plants growing alongside your pond can provide plenty of shade from the outside. Blue Flag Iris and Dwarf Cattail, for instance, planted on the south or west side will cast cool, shady shadows for your fish.
  • Get Creative with Canopies: If planting trees or plants isn’t an option, consider installing a tent or canopy over part of your pond. In addition to creating protection from the sunshine, a canopy can also add some dramatic flair to your backyard décor.
  • Aquatic Plants: Aquatic plants, like water lilies and water hyacinth, create scads of underwater shade for your finned pals. Simply plant lilies in baskets or plant bags and place them in strategic spots around your pond or toss in water hyacinth to create a floating hideout.
  • Fish Shelters: For a super easy solution, drop some fish shelters, like our Nycon Koi Kastle Fish Shelter, in your water garden. Another option is to create fish caves with carefully positioned rocks. They’ll create a shady shelter that’ll protect the fish from sun – and predators.

A word of advice: Don’t over shade your pond. You still want to maintain an area with some sunlight, which helps bring out koi colors, keep the water a comfortable temperature and help your plants grow.

If you think your fish are already showing signs of heat stress, check your water temperature with a pond thermometer, like Pond Logic® Floating Pond Thermometer, and do a partial water change if the water temperatures reach the high 70s or above. You might also want to add some pond salt, which will help gill function and reduce fish stress, as well as some Stress Reducer PLUS, which alleviates stress, restores a healthy slime coat and removes dangerous toxins from the water.

A: If you want to get the most out of your beneficial bacteria, control excess amounts of nutrients and have a pond full of healthy fish, you need to add Pond Logic® EcoBoost™ to your maintenance routine. Think of it like a multivitamin for your pond; it enhances what you already do to create a clean, clear ecosystem.

Here’s what you need to know about the benefits of EcoBoost™ and how to effectively use it in your pond or lake.

Benefits Aplenty

EcoBoost™ has three main functions. It binds excess phosphates, enhances the growth of natural bacteria and adds trace minerals that fish need to thrive.

Phosphates – which enter a pond or lake via lawn fertilizer and storm drain runoff – can wreak havoc in an aquatic ecosystem. They act as algae and aquatic plant growth steroids, causing algae blooms, weed proliferation and muck buildup. If left untreated, the result is oxygen depletion and poor fish health.

EcoBoost™ helps to control those phosphates, and in doing so it acts as a boost for the natural bacteria living in your pond. As the beneficial microorganisms found in MuckAway™ and PondClear™ gobble through organic debris on the bottom of your pond and suspended in the water column, EcoBoost™ binds excess phosphates and removes them from the water.

In addition, more than 80 trace minerals found in EcoBoost™ promote fish health and fast growth. It’s also safe for other aquatic critters as well as horses, livestock, birds, pets and wildlife.

Easy to Apply

EcoBoost™ comes as a powder that you simply mix with 2 to 3 gallons water in a pail and pour along the shoreline of your lake. You can apply it every two weeks, or on a routine schedule along with MuckAway™ and PondClear™. It has no temperature restrictions, so you can use it all year long.

If you use chemical algaecides or herbicides, be sure to wait for three days before adding EcoBoost™ and your beneficial bacteria products.

This spring, try adding EcoBoost™ to your maintenance routine. You’ll enjoy clear water and healthier game fish.

How do fish go dormant? Are they really asleep? – Decorative Water Gardens Q & A

With the warm days of summer now a distant memory and fall following in its footsteps your Koi are left with a few months of cold weather with nothing to do but relax. Since they don’t have miniature submerged Koi calendars to check what is it that tells your fish it is time to hibernate?

Koi are cold blooded creatures which means their body temperatures and activity levels are directly correlated with the ambient temperature. Koi are active and alert when their environment is warm and will start to slow down as the water temperature decreases. Once the water temperatures start to dip below 46°F your fish tend to stop eating and will retreat to the bottom of the pond. Your fish use the decrease in temperature along with the shortening day lengths as a trigger to prepare for winter. As the water begins to cool your fish will become less active as their bodily functions slow down. Less activity means a slower digestive process, less demand for food. It is this decrease in food digestion that warrants the use of wheat germ based foods like Pond Logic® Spring & Fall Fish Food. These types of food are easier to digest that regular food reducing the risk of leaving undigested food to rot inside a dormant fish which can potentially be fatal.

As the temperatures continue to decline towards 40°F, the blood flow and respiratory rate of the fish will drop to an extremely low rate where their body is hardly functioning. You may hear people say that your Koi are sleeping in the winter and while fish do sleep this goes way beyond the standard drop in bodily functions associated with some much needed shut-eye. This extreme internal slow down ensure survival with even the most limited resources with cases of dormant fish lasting 150 days without food.

The whole over-wintering scenario sounds a little extreme to us but it is truly a natural and normal process for your fish. They do not require much attention in the winter but there are a few things you can do to ensure their winter break is a success. When a layer of ice begins to form over the pond, maintain an opening for gas exchange using your aerator or a de-icer. Also, make sure you feed with a cold weather formulated fish food as water temperatures approach 50° so your fish are able to safely digest it before hibernation begins. You can use a pond thermometer to keep track of the water temperature in your water garden.
