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

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.

We just cleaned out all the sand in our above ground pool filter and added the blue balls instead. Our pool was a bit cloudy so we bought this product after I did some research on YouTube... this stuff is AWESOME! our pool has never looked so clear and blue. I will definitely buy this again and recommend it to my friends and family.

People of a certain age will remember the ad phrase "A little dab will do ya". Well in this case, just a little bit of Super Blue in my 36000 gallon pool cleared it up in one day. I keep a bottle of it at all times and it's one of the first things I use when opening the pool in spring. It's a covered pool (poolcoversinc.com) but stuff does still manage to get in there. Use this, then the pool vacuum and all the fine silt is gone.

After two applications, it seems ok.

Impressed with this product. The super blue really helps to make the pool look extra clear and crisp. Normal chlorine and a good filter is fine but for seeing clear across the pool under water, you can’t beat it. Takes out almost all major or minor cloudiness, assume all your chems and water are balanced.

Very good

My pool was cloudy and all my levels were great. I poured this in and in a day or 2 it cleared up!! My go 2

Glad to see the reviews that some had good results.But for me, after 6 weeks of thunder storms and downpours my pool water developed a green Algae bloom.Even though I shocked it after every rain storm, it literally turned into Pea soup and could not see even one inch below the surface of the water.During this time, every morning I Vacuumed the pool, then removed the filter element and cleaned it with the hose.The next morning nothing changed.I then tried Algaecide, Super Blue Pool Clarifier, and kept using the Shock each day, and again Vacuum the pool the next day, remove the filter element and clean it, but Nothing changed after a week.So, I kept searching the web for a solution.And, I found a video different from all the others that kept talking about Algaecide and water Clarifier.In the video, they did start talking about Algaecides and water Clarifier, But.......Then they went on to say when you have what I have happening to my pool water, I needed to simply Shock the hell out of the water.So feeling it was my last resort, I started Shocking my pool every day with HTH Pool Care Shock Advanced for Swimming Pools.Each day for 7 days I Shocked the water with 4, 1 pound packets of the HTH Shock, and the next morning Vacuum the pool, remove the filter element and clean it.Then Shock it again with 4 packets of HTH.Each day I could see a slight improvement in the water.Then, each day I did this, the water cleared up more and more until FINALLY, the water was now Crystal Clear by the 7th day.Just info for what it's worth.
