First post! - after lurking on here for several hours or possibly days... This will be my first-ever pool to own. It is currently finished to gunite/tile/coping stage now, but lots of work remains with drains, outdoor bathroom, decks, gunite "boulders", etc still to come. I found this site after the PB had already ordered my trichlor chlorinator and Nature2 and now feel a little dumb for that, but I plan to use it at first to get CYA up, monitor my levels, and take the Nature2 canister out after a couple of months. Then I will switch to 12.5% LC for my chlorination except when on vacation.
I live in an area with a community water provider that is largely well based. We have known problems with killing every plant known to man mainly due to salinity issues. I ordered the TF test kit + sodium test and ran test on my fill water:
pH - 8.2
TA - 450
CH - 75
Na - 600 ppm (still better than the 1000 ppm from my well on my property I use for irrigation!)
I already expect my pool to have huge acid requirements initially, considering multiple waterfalls, new plaster, and my fill water pH/TA. At this point I'm looking at running the waterfalls most of the time and just sucking it up and dumping whatever acid is called for into the pool until the TA presumably lowers itself to a reasonable level (since I'm basically doing what is outlined in Pool School to lower TA). I also expect to have to add some Calcium to help keep the CSI in appropriate range with the new plaster.
Anyone have any specific insight/recommendations/criticism regarding my plan? (FWIW pool size is ~35-40,000 gallons by my estimate. Forgot to put that in my sig)
