After several days of adding chlorine, brushing, and filtering, water has been looking nice and clear the past few days although brushing does lead to some little dusty light yellowish-brown clouds that I *hope* aren't live mustard algae. Took sample to Leslie's a couple days ago and they said chlorine was above 10PPM, too high for them to do a full test. Took another sample in today (my FAS-DPD kit is on order) and results are:
FAC 5
TAC 5
pH 7.4
TA 120
Calcium Hardness 200
CYA 50
TDS 1300
Phosphates 400 (Leslie's guy says PO4's are "really high" but from what I've read here, i just need to make sure I keep the Chlorine level up, right?)
So from the FAC/CYA chart and calculator it looks like I should add another 21 oz. of 10% liquid chlorine to move from current FAC to target of 6, right?
Thanks! It's great to be able to post questions to pool users who *aren't* trying to sell me more pool chemicals!
