When to use polyquat?

[littleHeidi]

Why the sarcasm? I was being blasted for not following everyone's advice on here when I WAS. I used the polyquat like Michael suggested and was simply thanking him. I can't help the bleach didn't work for me like. I poured almost 50 gallons in there and was getting nowhere. I greatly appreciate this forum and all the help I've gotten from it. I apologize if you read anything else into my post.

did u have the pump running overnight after u added the algecide? i have had mine running for 3 days now and still have brown foam on top of the water. when i turn the pump off, the foam dissapears. but it comes back again when i start the pump again.

vwb1975,
Polyquat does not generally cause foaming, which is why it's the only algaecide advocated around this forum. Algaecides that contain copper usually are the culprit when you have foaming issues.

ammonia based algaecides also are notorious for foaming.

Once you have an algae bloom, you have to fight it with chlorine. You have to keep the free chlorine at shock level constantly, but shock level is dependent on how much stabilizer you have.

You now also have to fight the foaming, which the chlorine will do.

You'll need to post your numbers:
FC,
CC
pH
Tot Alk
Stabilizer (CYA)
and
Calcium.
