Q: I thought I did a successful chemical treatment, but why are the weeds coming back?

Barney – Andalusia, AL

A: Treating weeds is a tricky task. Despite dosing them with aquatic herbicides to clear your pond or lake of plant pests, they seem to grow back over and over again. It seems like a never-ending cycle!

Why does this happen?

Well, chemical treatments have their benefits and drawbacks: On one hand, they work great as a quick fix to decimate actively growing weeds. But once those plants die, they become a food source for future weeds and algae, acting as a fertilizer for the very things you’re trying to get rid of. The herbicides do nothing to prevent future growth, and so you’re left with yet another growth spurt of pond weeds, which you’ll then treat with chemical herbicides – and around you’ll go again.

So how do you break the cycle? Here’s a four-step approach that will help put an end to it.

  1. Remove the Dead Weeds: Once the weeds have browned, use a Pond & Beach Rake or PondSkim™ Debris Skimmer to remove as much dead material from the water as possible. This prevents dead plant material and muck from accumulating and fertilizing future weed growth.
  2. Be Proactive: Debris will still find its way into your pond, so add some beneficial bacteria to the water to manage the excess nutrients before they feed your weeds. The products found in the ClearPAC® PLUS Pond Care Packages – including PondClear™ and EcoBoost™ for suspended debris, and MuckAway™ for accumulated bottom-of-the-pond debris – naturally break down that organic material.
  3. Add Aeration: If you don’t have one already, install a Airmax® PondSeries™ Aeration System that’s sized for your pond or lake. By circulating and adding oxygen to the water column, the beneficial bacteria will thrive. In turn, they’ll eat through even more debris and prevent weed and algae growth.
  4. Shade and Color: Also found in the ClearPAC® Plus package is Pond Dye, another offensive tactic in your battle against aquatic weeds. Pond dye shades the water blue or black, preventing ultraviolet light from reaching the plants.

Throughout the spring and summer, weeds will grow. But with some pond management practices, you can keep those pesky plants to a minimum.

Why are my goldfish changing colors? – Water Garden & Feature Q & A

Why are my goldfish changing color?

Water Gardens & Features Q & A

Q: Why are my goldfish changing colors? – Emily in New York

A: Whether you have a traditional goldfish in your pond or one of the many fancy varieties, you may notice their colors change over time – don’t worry. It doesn’t necessarily mean your fish have some sort of disease! In most cases, it’s normal for goldfish to change color. So before you start dumping antibiotics in your pond, first consider these possibilities:

Genetics

Goldfish naturally change color as they age. Though most do so during their first year or two of life, others change throughout their lifetime. Fish experts have identified two different types of color changes in fish: physiological and morphological.

Physiological changes occur when the pigments in the cells either spread out, which makes the colors more pronounced, or when the pigment clusters in the center, which makes the colors more muted. Morphological changes occur when the actual number of pigments in the cells increase or decrease. An example of a morphological change is when a black goldfish starts to turn orange or a young goldfish loses its black markings as it ages. In this case, as the fish matures, it’s losing its black pigment cells.

How and when their colors change really depends upon their individual genetic makeup. Inexpensive goldfish whose parents are unknown can change in unpredictable ways, while expensive show-quality fish will be a bit more predictable.

Color-Enhancing Foods

Certain types of food, like Pond Logic Growth & Color Fish Food, can accentuate subdued colors in goldfish, too. Sometimes, a dull orange goldfish can be made a deeper shade of red with these specially formulated diets, which contain natural color-enhancing supplements like spirulina, beta glucan, vitamin E and vitamin C.

Keep in mind, however, that some of these color-enhancers may affect other colors, too. White areas on calico orandas, for instance, may take on an orange hue – which may not be the look you’re going for.

Illness, Poor Water Quality

If your goldfish’s color becomes very dull or it starts to become inactive, that could be a sign of illness or poor water quality. Use a test kit, like the Pond Care Master Test Kit, to check your water quality, including your pH, ammonia and nitrite levels. Then, if necessary, add a broad-spectrum medication, like Pond Care’s MelaFix or PimaFix, to treat parasites or bacterial infections your fish may have.
