    • Works great. Stronger than I thought.

Review Image by WatchandjewelryLoft WatchandjewelryLoft
I have an 18'x42" Coleman pool. I've been using this since I bought the pool. I supplement with 3" tablets in a floater. I was over chlorinating going by the instructions for "shocking." I've slowly dropped the amount using trial and error. Now I can keep the levels stable with 1-2 tablets in the floater and maybe 8oz or so of the granules as needed. Even through the crazy heat we've had in South Alabama this year. I think I can taper it off even more as the temperatures drop. Makes for keeping the pool crystal clear, super easy. ... show more

    • Misleading title
Size: 2 Pound
This product is not a bucket it is a container so don't expect a bucket of actual product it's misleading in the description but it is the product it's a chintzy little tube style container that is easily cracked

I have finally found a chlorine that give me crystal clear water. Pool stays clear until next chlorination day, usually once week in summer.

    • A little Expensive, but worth it
Size: 5 Pound
With chlorine prices going up, this product is great. I try not to buy mixed chlorine as it can negatively affect your pool. Just wish it was cheaper.
