Found that my local club had in stock even though online said they were out. This is the first season I'm using this algaecide hadn't known Sam's had their own brand and for the price I'm giving it a try. The ingredients are the same as some other algecides I have used, paying for a quart what these two gallons cost. I normally use as a preventative, so as of now can't say how it works to get rid of algae and as long as my pool stays algae free I guess I can say it works. Oh, had some bubbles after adding intial dose, no foaming, you just have to be careful to not add more than what it says to.

Worked great

Low content. 55%

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

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

Too much foam.

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
