So, thanks to this forum and the TFP pool test kit, I have been taking care of my pool for the past two years after having my pool built. Things have been going pretty good overall, but prior to going on vacation, I must have accidentally added a bit too much stabilizer; I normally keep the CYA at 50-60 and its up at about 80. I didn't think that was a big deal, but now I cannot get and keep my FC levels above 1ppm.
The kids have been using the pool a bunch, so I thought maybe that was the 'problem'. About 4 nights ago, I ran a boost on the SWG at 90% for 10hrs. It got the FC level to 2ppm, but within a few days its back down to 0.5ppm. I normally run the SWG 70% in the summer but due to the FC levels, I bumped it up to 85% and added a couple hours. Still no change.
I thought maybe the SWG was going bad, so I took it out for a quick check and everything looks really good, and there are no error messages or anything on the display (pool builder said this would happen if it went bad). Still, I put a hose on the return closest to the pump and filled my sample cup. With the SWG operating at 85%, I was only getting 1ppm of FC in the water coming out of the return. Of course the builder mentioned checking phosphates and from what little I have read here, that seems like a waste of time.
I'm thinking my elevated CYA level is the issue but want to get some expert advice. Last log values from yesterday are below.
FC - 0.5ppm
CC - 0.5ppm
pH - 7.4
TA - 70
CH - 325
CYA - 80
TEMP - 91
SALT - 3700
CSI -0.38
