Wow - This stuff works!
Wow - this stuff works! Followed the instructions & woke up to a much improved yellow algae attack. The next morning, the pool looked like new. This was my FIRST time using Yellow Out - pretty sure it won't be my last... AWESOME

Yellow Out Swimming Pool Chlorine 2 lbs. works every time I get yellow algae. It arrived fast and is an excellent price.

A Must-Have for Texas Pool Owners
iving in Texas, I deal with stubborn dark yellow algae on my pool walls every single year. It doesn't seem to matter how much work I put into keeping the pH and chlorine levels exactly right—the yellow spots always find a way back. This Yellow Out treatment is the only thing that actually works for me. When you follow the shock process described on the bottle, it cleans everything up completely. The best part is that I barely have to brush the walls at all; the chemicals do the heavy lifting, and the pool looks back to new in no time. If you’re tired of fighting mustard algae that won't go away with regular chlorine, this is definitely the solution.

Works either way twice the amount.
Works great but only when I used twice the amount.

No more 'green' pool
In conjunction with 'regular' pool shock, this product knocked out our 'green' pool and cleared it up quickly! Very happy to have a clean, clear pool again.

Don't waste your money
Did absolutely nothing for my pool. Ended up purchasing stop yellow to clear the yellow algae we get every year at this time.

Another later than advertised Prime delivery
Product and delivery is/was fine except it was 2 days later than advertised for prime members. This seems to becoming an Amazon trend...late deliveries.

It works!!
Most important thing to know is that it works for our pool while chlorine alone did not.
