The 'green monster' in the back yard necessitated something be done...
Pre-TFP discovery I took a water sample to Leslie's (I now know better)
Their numbers:
FAC -2 (OK) (Their words)
TAC -2 (OK)
CH -90 (Low)
CYA -100 (high)
TA -180 (high)
pH -7.6 (OK)
copper - 0 (OK)
iron - 0 (OK)
TDS - 500 (OK)
phosphates - 200 (high)
They wanted me to add acid for TA; which I did and almost 8 lbs of shock which I did. After no miracles occurred I started to research online. (I 'inherited' the care of this pool) I found TFP and it sounded like a common-sense approach to pool care so here I am. I determined I needed to SLAM the pool, but with a high CYA I would try and remedy that while I was waiting on your test kit. I lowered the pool level by almost 1/2 and refilled thinking that would lower my CYA by almost half (closer to the normal range) and b) help with how much liquid chlorine it would take? I began adding liquid chlorine (10%). After 2 days and 33 gallon jugs with absolutely no change in green I finally achieved 31 ppm. (Erroneous number for CYA @ 100; not sure why I decided to use that number as the target as I did consult your charts) I did a test for CYA soon after I started adding chlorine and got the number of 100 (original number from Leslie's pre drain/fill
). Continued to dump more chlorine/money into pool in an attempt to maintain 31. (It would drop to 15-25 overnight) In performing another CYA test this morning, it showed 80. I think CYA dropped slightly with back-washing sand filter/refilling? Poking around on TFP today I realized that with such a high CYA the SLAM is difficult (impossible?) and my maintenance chlorine PPM will always be high. I have performed no other tests other than FC, TC (2-3) and CYA because I was SLAMing. I am aerating (return nozzle breaking surface) to try to help with TA; backwashing sand filter for 5 minutes every 2-3 days; running leaf robot several times a day in an attempt to 'brush' the bottom of the pool (the bottom is not visible at all) ; blindly brushing edges/bottom occasionally. At 5 days in with very little progress should I quit, partial-drain, re-fill, test and adjust or carry-on?
Please forgive my long post. I'm trying to give as much information as I can.
