Doheny's Super Algaecide Plus | Pro-Grade | Effective Against Most Algae Types | 7.1% Chelated Copper (Reduces Staining) | Non-Foaming, No Clouding | Safe to Swim After Use | 4 x 40oz Bottles (160oz)

Works fast! All algae is gone! Great size for price.

At first I was skeptical but hopeful on this algaecide. I had read some less than ideal reviews, but I bought it anyway, hoping it would work. Turns out that it turned my dark green pool into a nice bright blue in TWO DAYS. I added the recommended amount according to the bottle, in conjunction with two pounds of shock treatment. All the algae is now dead or dying, and I couldn't be happier. I was afraid I was going to have to drain the pool for a deep scrub or a resurface, but now I don't have to. The water didn't clarify much, but I have another product for that to test next. It did definitely clean the water up a bunch though. This 4 pack is a fantastic deal. My pool looks good again and well enough to enjoy soon.

Oh this is a reasonable buy sn I trust the mfg. past experience says they have this algaecide perfect… and works fast. Just make sure the filter is backwashed

Only two applications for now every thing is going well.

Pool use:keeps algae from forming

This product is the best algicide I have tried and it works great.

Great product and a great price compared to local pool companies

This product does what it says. It might take a second does but it takes your pool from green to clean. I highly recommend this product
