So, I've always used liquid chlorine in my pool and have maintained good levels. I'm going away for a week and was going to try and use 2" Trichlor tabs I found at Ocean State Job Lot which I've never used before. My parents may come over to use the pool periodically so I don't want to bring it to shock level. They can't be bothered with any sort of pool maintenance. My question is how many trichlor tabs should I put in the floater? How long do those things last? I'm not worried about stabilizer levels right now because mine is on the low side anyways due to wall the water displacement from lots of rain we've had, so I could actually use some extra stabilizer. Just looking to properly use these things. Package says 1 tab per 8000 gallons per day? Do these things melt (or whatever the proper term is) in a day?
