GLB 71205-SP-02BX Super Blue Pool Clarifier, 64-Ounces (Packaging May Vary)

Love this product. Won’t use anything else in my pools. We have 2 properties one has an in-ground and one has an above-ground pool. Works great in both.

This item works very well, crystal clear water right away. Great value for the money. It did not seem to affect the chlorine.

My pool was looking pretty funky after I forgot to shock it after a big party here. My robot wasn't doing the trick for the algae control, so I needed to bring in the big guns. This is probably my 20th bottle of this stuff, it really works great for algae and general dingy water. You just pour a cup or so into the deep end of your pool, let the pumps cycle it through, and then your pool robot will get the stuff off the bottom. Easy. I only buy it when I really need it, but the contrast of before and after is stark. I didn't think to snap pictures, but I will next time. My only gripe is that the bottle looks like a gallon, but it's actually miniature, you get a whole lot less than you think you're getting, and it surprises me every time. It looks like a 1-gallon jug, it's not, it's much smaller.

I use this product has a weekly maintenance to keep the pool clear. It works well, not fantastic, but well. I usually do In The Swim clarifier, but with a little price increase I decided to try this. If my pool gets a little cloudy, it works but sometimes takes a day or two longer than the In The Swim product. Instructions are pretty easy and straight forward. Came not broken or leaking.

The cost for 2 bottles from Amazon was nothing compared to big box stores let alone local pool suppliers. One bottle will easily last me a year, as I only add a few ounces after I clean my filter cartridges. It definitely helps the filters catch smaller particulate, the water goes from clear to crystal in a few hours, and whether that is just because of his product, or the fact I keep my chlorine, pH and alkalinity well balanced is not something I am going to test to find out! All I know is that I bought 2 32oz bottles 1 year ago and have used half the bottle - while the price went up, at the current price it would cost me less than $1.50 a month for my 20,000gal pool - even less than the bulk baking soda or Salt that I buy from Sam's club. If you are comparing clarifiers - remember there are 2 kinds - flocculant and Clarifier - this is a clarifier. Flocculant makes particles combine so they fall to the bottom of the pool to be vacuumed up. Clarifier makes them easier to get filtered by your pool filter. This is a great clarifier!

This stuff worked great. Have been trying relentlessly to get my pool clear and stop being so cloudy. Two treatments of this and crystal clear. Even after a week and a half of rain it is still clear

Poor mixing ability. Unless you brush after using globs of blue product remains foe some time

Works great. Just follow the directions
