Most of you are dealing with extensive algae blooms. And even though the quick and effective fix of Algae fix  does keep it at bay, extensive  use of it will stress your fish and plants. I tell most everyone who buys it that anything that will slow the growth of algae will also slow the grow of your aquatic plants. We have seen diminished growth on hyacinths and waterlilies with the constant use of Algae fix. And those plants could be working for you at no additional cost to keep your pond clean.

During the height of the season it is best to let more of the bacteria and plant growth provide the competition for nutrients against algae to keep your pond clear.  If you have a koi pond without plants try barley or phosphate removers to keep algae subdued.

Another factor of the heat is pond water temperature that exceeds 86 -87 degrees will stress your fish. It is harder for fish to get oxygen from hot water. Do not let your plants cover more than 60% of pond surface because plants will consume oxygen in the evening hours.
