Water Gardens & Features Q & A
Q: I am having a terrible time with green water in my water garden. What can I do? – Abby of California
A: It’s that time of year again when the fish are playing, flowers blooming and your backyard is once again becoming your peaceful retreat, except for that green water in your water garden. Like most of us water garden owners the highlight of our yard is our water feature but what fun are fish if you can’t see and enjoy them? Here are some considerations that may help you take back your water garden.
Filtration: Early in the season your filtration system may not be up to par with the amount of waste and debris left over from the winter months. A good spring clean out may be needed if there is an excessive amount of debris in the bottom of the water garden. If your water garden is relatively clean use a pond vacuum or application of natural bacteria may help get you on your way. This is the time of year to wash out or replace your filter pads to prepare for the coming season.
Fish Load: Have your fish been busy? If your spacious water garden is becoming a full house, it may be time to find a few friends and share the wealth. Overcrowding is a common source for green water since the filtration system may not be large enough to handle the amount of waste being produced. A simple rule of thumb to ensure room for your fish is 1 fish for every 10 sq. ft. of surface area.
Plant Coverage or Shade: We recommend 40-60% plant coverage in your water garden. This adds to your filtration, since the plants are up taking their nutrients from the water. They also provide the added benefit of shade to help protect your fish from predators. A variety of plants should be used, including: bog(marginal), submerged, water lilies or floating plants. If your not sure what to get, you can check out our aquatic plant packages.

What about a UV filter?: You might be wondering why UV filtration wasn’t mentioned as a solution to green water. Indeed, it is a solution but…it is also can be a band-aid covering up a deeper problem. Always be sure that your filtration is adequate and you don’t have too many fish! You should also be using your test kit to make sure your water is safe for your fish. If everything checks
out ok a UV may be a good tool as long as it is not the only one. Just remember if everything mentioned above is in check the green water should take care of itself and you will have a healthier overall ecosystem.
