since we got enough rain again last night to overflow my pool, and i didnt test pH in two days i went out this morning and ran a full battery of tests minus CYA:
FC - 6 - added 10oz 8% per pool calc to bump to 7
CC - .5 - probaby due to rain
TA - 100
CH - 60
pH - 7.2 - it has been steady 7.6 with me testing every other day and doing nothing for last 4 weeks, even if we run the **** out of waterfall, it hasnt changed.
I added 22 oz by volume of Borax using the same oz measuring cup i use for bleach and everything else. i broadcast spreaded it all the way around the pool with pump going. according to pool calc, this should have bumped it up to 7.5.
waited 1 hour with pump circulating... went back out and tested again... 8.0+
what in the world? i know i used 5 drops on each test, going about 1 drop per second for each, i swirled it, i did everything right as far as i know. the color was easy to read.
i dont understand. i had this happen before. since 8.0 isnt going to hurt an intex pool too bad i just left it be and it gradually over about a week went down to 7.6. now its sky high again.
since i seriously doubt this is a pool calculator problem... what am i doing wrong?
