I have an Autopilot Total Control system. Salt is at 3200. ZeoSand (or similar-sounding products) sounds like a good substitute for sand in my Hayward S310T, but ZeoSand requires a salt-water backwash from time to time to cleanse it of ammonia among other things. Since my water is already salty, I'm concerned about whether the salt in my pool water would constantly free up the ammonia and send it back into my pool. I would also like to use ZeoSand for its ability to take calcium out of the water (my pool is filled by water with a CH of 500). I would not want the salt in my poolwater to constantly wash the ZeoSand of calcium straight back into my pool, either.
Since a salt-water pool is not all that salty, though, maybe it would still work. Can you tell me if ZeoSand or a similar product is compatible with and remains effective in a SWG pool?
