I have been using BBB for a month and a half and everything seems great...
Water is crystal clear and never looked so good....
Today's test results:
Fc = 4
TA = 70
CH = 60
CYA = 30
PH = 7.2
I struggled with the CH test at first but am certain I have got it right after reading about fading end points etc. etc.
The fill water here is very soft and I have read all over the site about calcium hardness and I really can't find a comlelling reason to raise CH with fibreglass liner.
Since I have fibreglass pool, what reason do I have to raise CH?
I have some cal-hypo left over and think I'll just use that up to get the calcium up and finish up the old stock.
Also another observation is that I have been adding regular doses of liquid chlorine ever since I lowered pH to 7.2 to do my initial shock.
The pH had been rock solid ever since. It just won't budge off 7.2. Shouldn't it be drifting up over time?
