Update: I’ve been using for a few weeks now. I have a large pool. It’s summer right now and so temps range 90-100 degrees. I am adding 2 pucks a week. My pump will run 2 hours in the am and 4 hours in the pm. Pool is clean and clear! So far I’m happy and I received a replacement of my broken pucks.Edit: adding a star for customer service. I reached out to seller and they are making up for the broken pieces. I will update again once I use them for a bit and see how they work. So far the chlorine smell is strong. Not sure because of all the broken bits at the bottom of the bucket but hope the pieces I can use work well.Well I have to say I’ve ordered buckets of chlorine on Amazon before and I had not had a problem. That company wasn’t available any more so I tried this one. Unfortunately I received my bucket with a little over half of the pucks still in tact and in their wrapping. The rest of the bucket is a mess! Not happy at all. Will look elsewhere next order.
