I just received my TFTest 100 kit to replace an older Taylor K2006 because I want fresh reagents. When using the R9 dropper the drops came out faster than the other reagents or my Taylor kit R9 reagent and the drops were smaller than the other reagents or the Taylor kit R9 drops, maybe half the size. The result was it took 26 drops to measure TA, resulting in 260 but my old Taylor kit reagents took 9 drops, for a reading of 90 TA that was much closer to what I expected. Is the R9 vial in the TF100 kit different from the rest, resulting in smaller drop sizes? I don't trust the readings.
Second, I got CYA of about 110, so that needs to come down. How can lower it short of draining a lot of (expensive) water?
The pool is/was SWG but the salt cell is going bad and not generating so I was using chlorine tablets as I typically do over the winter. I got about 18 inches of rain over winter, which usually dilutes my pool chemistry.
My measurements
FC: 5.5
TC: 5.5
CH: 375
CYA: 110 (most likely due to the chlorine tablets)
TA: Taylor kit says 90, TFT 100 kit says 260
pH: 7.4
NaCl: 3000
Where do I start with the SLAM? Start dumping bleach in (assuming WalMart will sell me 16 gallons) or buy liquid chlorine from the pool store?
27k gal in-ground, pebble sheen surface, well water (soft water faucet), DE filter, salt water but SWG is not working
