Every time I go to Walmart, they are almost out. Went tonight and they are COMPLETELY out and said they don’t know when they will get more. I had to buy regular Clorox bleach. Not the concentrated stuff…just regular bleach. Will that be ok?? Any suggestions of where else to try? I do have some pucks (no idea what they are called lol) that the pool store sold me before I found this forum, but I’ve never used any as I think they are Cal-hypo and my pool has done so well with the liquid chlorine I didn’t want to mess anything up. Please help!!
