So... 3 full weeks into my first pool and everything seems to be going great thanks to all the help from you folks. Just learning some final tweaks for peace of mind really. Any help would be appreciated.
After week one I had these results from testing
FC goes down to about 4 and I bring it up to 7.5 or 8 every day. LOTS of sun on my pool.
CC 0
PH 7.8 +maybe
Alkilinity 120
CH 140
CYA ~ 50 or 60
So I added Muriatic Acid to bring down the PH. Tested again the same day. Changes were:
PH went from 7.8+ to 7.3
Alk went from 120 to 90 or 100
I left well enough alone.
After week 2...
FC good
CC 0
PH 7.5
ALK 100
CH 140
CYA ~55
Things looked pretty good. I noted a slight rise in PH.
After week 3 (yesterday)...
FC Good. Seems to steadily lose up to 4ppm daily depending on sun. I noticed on very cloudy days I lose less. As little as 2ppm a couple times.
CC 0
PH 7.7 another rise
ALK 100
CH 140
CYA ~55
So now Im wondering... PH is rising without a rise in Alk. .2 per week I am noting. Time for more acid I think. But from what I read my Alk should be between 90 and 120. If I use more acid, it seems I will drop below that 90 mark. (is that ok?) And if this keeps on?
On the pool return I have, there is nothing on the inside of the pool. Meaning that the return shoots straight into the pool 6" or so below the water line. There is nothing there for me to turn and make the water shoot lower. So... is it possible that the return ripples are aerating the water? Causing PH to rise? Is doesn't splash or bubble really but I do see rippling out for several feet from the return.
I'm looking to solve this before I add more acid because from what I read in pool school this seems like "aeration" causing this. But Im also 3 weeks into pool ownership. Any thoughts?
