I have a 1200 gallons pond that is infested with hair/ slime algae! The water is actually is very clear (morning), but is infested with hair algae that is killing my water plants. The slime floating algae appears after 4 pm that is when the sunlight hits the pond.
Nitrates are Close to 0, phosphate 0 , Gh 300, KH 150, PH 8.
Any help? (pond is 4 months old)
