I left my pool store and switched to BBB last month. I am having difficulty maintaining any kind of steady FC level and hope someone can perhaps enlighten me? I have the TF 100 for testing.(7pm)
Last night's readings (7pm):
FC - 7.5
CC - .5
TC - 8
pH - 7.5
T/A - 140
CH - Didn't take
CYA - 60
Readings from 9am this morning:
FC - 5.5
CC - .5
TC - 6
pH - 7.5
T/A - 170
CH - 370
CYA - 60
A little history: I started out w/CYA of over 100 about a month ago. Did partial drains and fills to get it down to 60. T/A was originally around 240. I have no means of aeration, though I tried multiple things to no avail. Eventually, the pH raised on its own so I could add Muratic Acid on two different occassions, resulting in a final T/A of 140-170. I had 6 children splashing and sliding into the pool on Sunday, but it failed to raise the pH so I could again use Muratic Acid.
My current problem is having to add so much Bleach to the pool on a daily basis. I am averaging 1.5 gals a day. I use the Chlorine/CYA chart and try to keep the FC level at the recommended Target rate of 7. Last night after the tests, I closed the cover on the pool, opened this morning to re-test. I dont understand how I can lose 2ppm of FC just overnight. By the end of the day, I will more than likely be down to around 3-4ppm.
Is this a normal situation? Is there anything else I can do? I have read several posts from members who only have to add a cup or two each day to maintain their desired levels. I realize my CYA is still high, but why can't I maintain the proper level with less bleach? It is very hot and humid here in Indiana (90s) and my pool gets full sun until 6pm. I can keep the cover closed, but it tends to heat up the water. Any suggestions would be welcomed.
