Swimming Pool Care Algae Guard, Swimming Pool Chemical, 32 fl oz

This product is amazing! My pool has never been this blue. We recently had a tropical storm come through our area dumping massive amounts of rain which caused an ugly mustard algae bloom. I must have dumped 5 gallons of chlorine into it over the course of a week and the algae wouldn't budge - it actually got worse. In desperation, I ordered this product. We put 14 fluid ounces in immediately. It lightened up the pool, but there was still some algae present, so we added the rest of the 32 ounce bottle the next day. Overnight the algae disappeared and the pool got even bluer as time went on.There is currently no chlorine left in the pool and it is still blue with no signs of algae. I put the last of the product in on Monday and today is Friday. This product works miracles. I wish I had known about it sooner as I could have saved myself a ton of money and grief.Other users have mentioned having trouble with foam. We have had zero foam. The only thing I can think is maybe the product is interacting with other chemicals present in their water, because we have had no foam and we used the whole bottle.Excellent product. I highly recommend for stubborn algae problems.

I thank the gentleman that steered buyers to this product. It’s likely my fault for not maintaining my pools chemistry balance, but each year I get these spots that I believe is mustard algae. Chlorine resistant yellowish looking spots that I just couldn’t get rid of. This product has worked to stop them. I may have a few small residual spots after treatment but I need a new plaster job anyway. I have a small waterfall and get very little sudsing, can swim within 24 hours and don’t turn green like someone may have mentioned. I keep my dog (who drinks pool water) away until I’ve added more water to the pool or it rains. A very good product to fight algae when you’ve let your guard down!

I have a 13,000 gallon small inground pool. It's a salt pool with a chlorinator. Summer heat here in AZ plus dust storms took a toll this summer. Should have cleaned my filters sooner. Started to get black algae. Shocked it and tried many things. I bought this, put in the whole 32 ounces in pool. Ran pool for 24 hours and it was all completely gone. It was crazy. No foaming or anything. Anyway, I don't write reviews but this one needed it. Mine was the Algae Guard + Ultra.

It worked but not as well as expected . I have a 16 X 24 pool had some Algae just wanted to keep it in check with the real hot weather. I used 1/2 the bottle and it still did not clear it all up. I will see if it does better as a keep Algae in check .

Muy bueno
