HTH67089 Swimming Pool Care Algae Guard Ultra, Swimming Pool Chemical, Long Lasting Formula, 32 fl oz

We have been using this for years.3 months of protection for inground pool. No issues - great product keeps pool crystal clear all Summer.

The 3 month one works good but they have sent the wrong one 3 times. Tied of returning.

This algae guard is one of the best I have found. It’s quick working! A bit prices, but you only need to use a small amount. Highly recommend it.

I put a few ounces of this product in the pool weekly all year. The pool has never had an algae problem.

We have been using this product for the last few years! It always keeps our pool looking beautiful!

product says it's for all types it is not talking about the sanitized Will work with Peroxide it has copper in it. Your pool will turn even greener as the copper turn green in Peroxide. My wife took a sample to the pool place which sold her like #300 plus of stuff we did not need, We were able to finally fix it once I researched it with Baquacil Metal Control for about $30. Everything Green is not algae but we did have some light algae as I was away foe several days and the Peroxide got to low. Hope this helps others who believe their pool place has experts and to ask the direct question before buying something.

I purchase this several times during the summer for our above ground pool. Keeps the algae at bay and clears it up quickly if I have let it get a little green.

I've used this product for 2 years to prevent algae in my pool.
