Hi - total pool newbie here!
We started looking after our pool ourselves a couple of weeks ago, having sacked the poolman who clearly wasn't doing his job.
The water looks very nice and clear, but I am having problems balancing pH and TA. The former always seems to be at around 7.8 - I add a pint of acid, it drops to 7.6, but next morning it's back at 7.8 or thereabouts.
TA has remained steady at 70. Yesterday I added 4 cups of baking soda to bring it up to 80, but this morning it's back at 70.
Today's numbers are:
FC = 2.0
TC = 2.0
TA = 70
CYA = 65
Ours is a 20,000 gallon AGP with Pebble Tec finish (concrete with ingrained pebbles). We are in California and the pool gets direct sunlight from sunrise till about 6 pm.
Many thanks for any suggestions.
