Can anyone tell about HTH Algaecide

I believe i will just take this back to Walmart. Think I'll just stick to the advice on this forum. Thanks.

I had mustard algae and looked for the "polyquat" that was recommended by this forum. Could not find in local stores, but found the exact same algeacide you mentioned here. Decided to use, did two treatments in 4 days and it cleared out the mustard algae with no side affects.

You are lucky, this is one of the algecides that we stock, although I do not recommend it. I have had a few customers buy it and come back and tell me their pools turned into a mountain of foam!

I have used a similar algecide and had foaming problems in the past. What is the best way to deal with the foam? I was also wondering about the whole idea of using any algecide. This may sound wierd but I was thinking that algae is one of the few visible signs of water problems and if the algecide works and prevents algae from growing it might mask other water poblems you might have?

Wait for it to subside. shocking sometimes helps.

This is very true. If your water chemistry is correct you will not have algae! Usually algae happens when the free chlorine is too low for the stabilzer level and the pH is out of range. It is a symptom of an improperly maintained pool! Keep your water chemisty on target and you won't have algae!

Thanks, my foaming is just about stopped now, I had a problem after the guys I hired to open my pool accidently overdosed with algecide (about 3x too much). I shocked the pool for several days and it was still foaming. It seemed to stop on it's own. Do you think these chemicals are being broken by the sun? My neighbor had the same problem from the same guys but worse (about 4.5X as much because of a smaller pool. Hers is still foaming. I guess there's no magic bullet for this. Just time and CL.

Can someone explain what causes the foaming. I have heard that one has to be careful of chlorine levels with linear quats. Can someone give advice about the optimal ph, chlorine levels for a product like this?
