1st post...
I am narrowing the chemistry targets based on all that I have learned thus far and just have a few questions. Please refer to my signature for the pool specifics. The pool is not heavily used (weekends with the family mostly).
I have been doing the pool chemistry adjustments since the first couple of weeks after startup and for the most part, it's been quite easy. Basically, it seems the pH increases steadily and I just have to add muriatic to keep it in range (about 1/2-3/4 gallon a week). I also occasionally add CYA. I was told that the acid is steadily needed because the pool finish is curing, but I am starting to wonder about that.
Typical Pool Values
FC=4
PH=7.6-8.2
TA=50-60
CH=200-300
CYA=40-80
Salt=2300-2500
Variances in Published Targets
Parameter/ Pool Finish&SWG Manual/ TFP Pool School
FC/2-3/4-6
TA/80-100/60-80
CH/200-400/350-450
CYA/30-50/70-80
Questions:
1. pH - Do you see any reason why I have to continually and steadily add acid each week?
2. FC - Are there any known issues associated with keeping the FC elevated above these targets? I am sure my equipment/finish is not unique.
3. TA - Same question as 2 for TA? Also, I tend to sit on the low end (50-60ppm) of the target and do not adjust it. Do you feel this is a concern? why?
4. CH - What is the basis for the higher calcium for plaster pools? If my pool finish info says to keep it at a lower value, should this override? I tend to sit at the lower end of the range. What is the concern about staying below the suggested range?
5. CYA - What is the concern with keeping the CYA at 30-60 or basis for keeping it at 70-80? Any known issues with the finish or equipment operating at the lower range?
Thanks again. Just trying to understand the differences to make final decisions about the targets.
