Hi,
Complete rework of our pool equipment two weeks ago. Upgraded to VSP, cartridge filter, SWG, suction-side vacuum, new heater because very old equipment froze, had leaks, performing poorly. We were SLAMming all the time, brushing, but still couldn’t keep algae away.
I dutifully shocked our 6 weeks no pump pool, added all the CYA they recommended. I had previously misjudged the size of our pool, but with the corrected size, my testing put me in a panic. FC was about 23, CYA was above 100. My installer tested same time and twice with a bigger Taylor kit and got 80 CYA and 10 FC. They calmed me down, it will drift down. Ok, 2 weeks later, yes the FC is 10, CYA is still about 100 maybe 110. A week ago, the pool got warm enough for SWG to come on, so I added bags of salt using charts and being conservative, yet my Taylor K-1766 that I bought a few days ago says 8000 ppm. Did I have salts dissolved in there before I added the salt? Is that where I went wrong? Or is the high FC interfering with more than the PH? Plus, at one point a few days ago, my SWG said to add 15Lbs of salt? The message is gone now.
I also added Boric Acid based on TFP recommendations for my size pool, but don’t have a test for that. Maybe I will order the strips.
Took sample to Leslie’s and am further confused, though I don’t put too much stock in their test numbers. (See the 3/23 1:59p results below with a note below about Leslie’s)
The pool water looks absolutely beautiful. Some brushing when I first added chlorine to get some algae off the sides. I read the salt post and it didn’t seem to ring any alarms about the apparent high NaCl level. Just wondering if this is a problem that needs to be solved urgently with a drain/refill. We got rain recently, but now be forecast for next 10 days.
