Floater pucks VS Skimmer pucks

[ThaSatelliteGuy]

Thank you so much for directing me to that "best guess chart"! It was like the jaws of life to clear my cranium! I dont know what was going thru my mind! I bought this pool (24'x52" Ultra) last February. Got the SWG off the jump, added the sand filter after figuring out the filtration was WAY undersized for this pool, and starting learning how the chemicals work. Didn't have ANY problems. (at least after I figured out the factory cartridge was not gonna handle my pollen levels and keep a clear pool) I mean NOTHING. I bet I didn't even shock but 3 or 4 times all year. Everyone here asking about CYA levels... DUH! I keep thinking "I dont have that problem", and I dont have THAT problem. My problem is that they're too low! For some reason I had it stuck in my head that I didn't have CYA last year. That the SWG did it's job and all was well. Total brain fart! I remember now specifically having to go to the pool store and get a gallon of liquid stabilizer since a SWG makes none. I just put 5lbs shock on Monday eve, two pucks, and Wed eve NO chlorine, and pool is tinting green again, WHAT? Last year 5lbs shock, and the levels would still be sky high 3 days later, but now I have nothing? Then I looked at the chart and it dawned on me... I've lost a LOT of water in the out-season. (I had a leak, and I totally forget the pool is filling overnight and screw my numbers up overfilling) As I checked my CYA and found none as I expected, I remembered last year I did have some... that little dot DID disappear last year... hmmm. Then it hit me like a ton of bricks. So... off to the pool store before work and before the sun has time to kill off my chlorine again.
As for the pucks, I took apart the SWG and cleaned it out, unstuck the flow-float, and gave it the vinegar treatment. Then raised my low salt level... again, and it seems to be working again for now. I just cant think of any other viable solution for sabotage other than SWG.
