I was in Leslie's a couple days ago and heard the guy at the counter mention that they will have a new chemical coming out this year that will reduce CYA. I told him I thought the only way to do that was to replace water and he said that it's brand new, never been on the market before.
Anyone heard of this? Is it legit? I would be nice if that were the case, but if I've learned anything at TFP it's to be skeptical of Pool Stores .
