In an ongoing effort to help people with green water and pond algae problems, it would be a mistake to not include the influence of fish in the equation.
In smaller ponds fish probably have more of an impact, both positive and potentially negative than anything else. On the positive side, few things can bring life and vitality into a pond any more than fish. If they’re colorful, you’ll find a rainbow of cascading colors shimmering under the water. It’s a beautiful thing.
On the other hand, fish must eat. And those that eat, must, well, get rid of what they eat. And this waste can definately increase nutrients in the water which, along with ample sunlight, can really boost algae growth along.
In this weeks video, we talk about how many fish is too many for a pond’s size and gallon amount. By knowing this information you’ll have a better chance of keeping your pond free from algae and more importantly you’ll avoid creating water quality problems (namely high ammonia levels) that can really cause problems for your fish.
