Excellent general-purpose algaecide that remains active in the pool water for 90 days. It is based on a low dose, organo copper complex, which is extremely effective and highly economical (32-Ounce Treats 20,000-Gallon pool water). It is effective in controlling all algae types. There is not a pool that won't benefit from this amazing product.

KEEPS MY POOL A NICE AQUA BLUE FOR WEEKS! USE THE WHOLE BOTTLE WHEN USING. THIS DOES NOT FOAM LIKE SOME OTHERS I HAVE USED...10,000 GAL POOL.

Great product for almost a full summer of algaecide treatment with two bottles. Only reason I put 4 stars is it's a bit pricey.

after putting this in, it seems like it triggered black algae to spread. The water was already balanced. Maybe it works for green algae only, because that has stayed gone (put it in before any algae bloomed this season), even after heavy rains, but the black algae is hanging in there!

Recommended dose for a 12,000 gal pool barely made a dent. Almost twice the amount had to be used to control green algae. If your pool has "pop ups", some fluid should be added through the skimmer for better distribution.

This by far is the best algaecide that is made. It clears algaecide very quickly and does not foam. It lasts all summmer
