Building a pool now and trying to decide on equipment. I keep reading advertisements how a salt water pool is so much nicer because you can run your FC at .5, then I keep reading blogs here that say I need a FC of 5-6. I also read blogs that say the FC needs to be the same whether Chlorine pool or a Salt Water Pool. Was hoping to run a low FC and supplement my water with UV. I read the postings here that the SUN is UV and I get that, but the sun grows algae, whereas the UV system (being much more potent) destroys algae . I am being pushed really hard by my pool builder to buy an ionizer (silver/copper) if I go SWG. Now I see that there is a chart for what FC is need for what CYA level is in your pool. Basically, I just want pool water that will not make people's skin itch or their hair to feel like straw or worse, turn into green straw. (don't we all?) Other problem is my town gets lots of sand storms and I am afraid that a cartridge filter will get plugged too quickly, yet do not really want to use a sand filter. Has anyone had good results with either singular or combined ionizer, ozone, UV system?
