Man Deja vu, I just finished posting this in another thread. Pool builders in Texas consider SWCGs the bogeyman for whatever reason. My personal theory is that this is because many pool builders also offer weekly service, and a SWCG is not conducive to that business model. Salt water pools are chlorine pools and vice versa. Period.
Tabs are not recommended with the TFP method since they allow for uncontrolled CYA increase. This will eventually lead a point where your water chemistry will not be manageable and you will need to drain. SWCG is undoubtedly the way to go, especially here in TX where the constant sun is a killer. Trust me, I'm already sick of jug lugging and it's only June.
