Easy pool closing and set up.
This product works great. Opening the pool was very easy as this product kept the sides clean. Just vacuum the bottom and run the filter balance your water and you’re good to go.
First time to use it. We will see what the outcome is this Spring.
Very competitive price and quick shipper. We will see how the pool water looks when we take the cover off in Spring.
It's milk
Not sure what you expect, but it's milk. It tastes like milk. It looks like milk. The package says it's milk. Works great in recipes, to drink, or to have with cereal. For milk, it's milk! Lol
Did you Shock your pool before adding? this?
So it worked for some but not others makes me think people didn't shock their pool before adding this product!!
Working good for now
It’s working well so far. I will have to come back and update my review it doesn’t. The only I’m concerned with is that it only says good for 15,000 gallons but it doesn’t tell you how much to use for smaller pools. I calculated approximately 3,000 gallons for my 8x12 ft pool. I had algae in my pool before closing so I put in 3/4 of the bottle and it made my total chlorine really high but the algae never came back.
