I'm moving into an Association and offered to help with the day to day maintenance of the pool (not the big stuff). As a first step I took a water sample today and got the following readings:
FC 10.5
CC 0
CYA > 100 (Yikes)
pH 7.0 (also yikes)
TA 70
CH 160
CSI -1.05
As expected, the pool service company is using a trichlor feeder to regulate chlorine levels, thus the very high CYA (and low pH). They will close the pool in about a month, so probably not much sense suggesting that the pool be partly drained a refilled at this point. I was going to suggest adding the calcium chloride to get the calcium hardness up to at least 400 ppm and either aerate of add Borax to get the ph up to 7.6. (Not sure they have a means to aerate the pool.) Also was going to suggest they turn off the chlorine feeder for the rest of the season and use liquid chlorine for the next month (and also use it as the primary source of chlorine next year).
What would be the best order to address these adjustments? Should the Borax (if aerating is not possible) and calcium chloride be added incrementally over 2-3 days. Thanks.
