Bought a house last August, pool was covered (should have been my first warning). It was disclosed in the sale that the SWG board needed replacing when opened in the spring. Pool was not properly or truly closed, obviously cover just thrown over. Took cover off last week and I have the Everglades in my backyard. Read through Pool School info about slamming but trying to determine where to start. Did water chemistry using FAS-DPD kit. Pool is 25,000 gallons, fiberglass, Hayward SWG, Pentair 1.5 pump, Sand Filter.
pH - very low (yellow in color)
FC - 0
TA - 0? - turned red immediately
CH - 100
CYA > 100 (under the lettering saying CYA on test chamber so maybe 150 or greater)
Do I do a partial drain and fill (likely multiples since fiberglass) to lower CYA before slamming as won't be able to hit shock levels of FC. Then adjust pH before SLAM? Was looking at buying the 10% liquid chlorine (lots of it) but is something else going to do better?
Thanks
