We recently renovated about a 3/4 acre pond in East Texas. After about a 5 inch rain a week or two ago, it filled completely. We were planning to add Alum in the next week or two to clear the muddy water before we started to stock.
Practically overnight (certainly within 24 hrs) we noticed the water started to turn green. You can see how the left side of the picture below the water is still muddy while the right side of the picture the water is now green. Who knows, by morning time our whole pond may have green water.
Is this normal???? Can we/should we still try to clear it with Alum?????
