I use an Intex Krystal Clear 2,500 gph cartridge pump right now. Really considering switching to a sand filter. But at the same time, was also thinking of switching to a SWG.
I have some dust/pollen/dirt that keeps accumulating in the creases of my pool, and if I go 3-4 days without vacuuming it builds up and bothers me. I passed my OCLT twice, two weeks apart, without shocking and with only .5 ppm loss, so I'm pretty sure it isn't Algae, which is what I was thinking at first. Also have either 0 or .5 CC, so don't think it's an algae problem. Hoping the sand filters more dust/pollen out so I don't have to vacuum every 2-3 days (I'm kind of OCD and don't want ANYTHING on the bottom, lol).
Considering switching to a SWG so that I can just "set it and forget it" lol. Tired of pouring bleach every day or two, and sometimes when I get really really busy I don't have time to test and worry about chlorine level floating down to below minimum and having an algae bloom. Had that happen at the beginning of May and it was not fun, and all because I ran out of bleach and didn't have time to get to the store and buy bleach two evenings in a row! My son is special needs (heart problems), we spend a lot of time in a major city 2 hours away for procedures and tests and hospital stays, and I'm not home every day to test/treat. Plus, he's 8, so he's in the pool as much as possible, lol, and his skin is pretty sensitive and I'm hoping the salt will help with that a little.
So anyway, I since I've never used either a SWG or a sand filter, is there any drawback or benefits to having one pump/unit do both things?? Intex has a combo unit Amazon.com : Intex 120V Krystal Clear Sand Filter Pump Garden
Or, I can do a separate sand filter and add a SWG to the loop if there are benefits to setting it up this way. Any input??
