Worked great

This worked so well for my outdoor pond. My water went from green to Crystal Clear in 24 hours yes I know this is made for a pool but works very well in a pond. I'm stocking up for next year Supply

I bought this product 3 weeks ago, I had a problem with black yellow and green algae in a 20x40 ft in ground concrete pool which is 30 years old. After 3 -12 oz applications all of the algae is gone! No foaming problem it just worked extremely well

Too much foam.

This used to be a decent product. Was clear, now it's blue. I didn't think anything of it at the time when I poured an ENTIRE BOTTLE of it into my green pool water last night, and shocked it with three bags of shock every 4 hours, three times. Still green. Going to take back the empty bottle and try for a refund.. HA

One quart of angry egg worked for an entire year in 2015. I bought the 2 gallon pack expecting this to last at least 3 years… HA HA HA!!! After ensuring the chemistry was correct, I used 1/2 gallon on a 7000 gallon pool and the algae came back 1.5 months later… I dumped in the other 1/2 gallon last week and the algae is already coming back and the pool reeks of soap. I'll NEVER buy that trash again… I'll use pennys and get better results

This product helped me out where many others have failed. Awesome!

Love this product my pool loves it too So mad my Sam's doesn't have in stock this year

Works ok ,right price
