| This time of year I am netting out cold water algae, which is a type of string algae that disappears (dies) when the water warms up. A bit is one thing too much is another, it can cause the pH to fluctuate and clog the filters. If it all dies at once it can make a huge mess and health hazzard to the fish.
I always recommend hand removal to keep it in check, once the pond is balanced it should go away on its own. By taking it out, you are also removing the nutrients it has 'eaten' |
