HTH 52038 Swimming Pool Care Green to Blue, Advanced Shock System, 2-Step Swimming Pool Care Solution, 1 Kit

We have well water with a touch of sulpher in it. The chemicals I usually have to start out with is alot. So I tried this and it works amazingly. I did have to wait an extra day for everything to sink to bottom to vacuum but I think it was because of my type of water. Very simple steps and end results worked very well for me. Highly recommend

There is no better way of dealing with an algae bloom than with Green to Blue. Quick, effective and inexpensive.

I opened up my pool this year and it was full blown swamp. Mosquito larvae, full of algae etc just bad bad bad. I worked diligently with my pool guy to try to fix the problem without draining- and after hundreds of dollars worth of chemicals nothing worked. I joined a fb group where everyone raved about this product so I said what the heck let me try it. Pool was light green but so incredibly cloudy for weeks on end. So anyway I put the “step 1” product in around my pool and disbursed it as it says so on the directions. Then I added “step 2” which was terrifying because it made the pool dark green but I just ran filter on circulate for an hour and then I shut it off. I woke up this morning to a crystal clear pool. The entire base layer was layered with debris/dead algae so I bypassed my filter and used my vacuum via the siphon method and very slowly vacuumed it all up. By 11am my kids were in the pool having the time of their lives. GREAT PRODUCT!!!!!!!!

This treatment was highly effective as my chlorine levels were much improved by next day. This is my first experience so I’m looking forward to additional experience and a great looking pool.

Works as described. Don’t be alarmed by the rusty color, apparently that’s normal. FYI, you aren’t supposed to use clarifiers with filter balls so if you use those maybe don’t use this product, or remove them after and clean if you have to.
