Newbie pH problem

[Lakedaisy]

Thanks all.  One thing I have learned here is to let things go a few days before re-checking.

I just finished refilling my spa.  Ph is on the low side (7.2).  Experience says wait before adjusting.  By tomorrow morning, Ph will be 8+.  My TA is probably around 300.  I adjust slowly since I only have time on weekends.  By the time my Ph is solidly within range it'll be time to change the water again (4 months).

Just as I predicted - off the scale high 8.2+.  The best thing is to learn your water.  No one else's is the same.

Have you tried getting your alk down first?

Try making sure your air intakes are shut off when not using the tub. Airating water will cause ph to raise

Things seem to be going ok w/ my spa water.  pH staying around 7.4-7.5, TA 100,  calcium 130.  Trying to get the dichlor right now.

I was putting 2 tsp each night when my wife and get out.  I haven't been testing the water chlorine level 15 minutes and 2 hours later as suggested by the 'Northman style' - which I have decided to try.  Anyway after putting 2 tsp in last night the chlorine was at 13ppm 15 minutes later. And 5ppm 2 hours later.

Tonight I only put 1 tsp in after we both got out.  Chlorine was 5pp 15 minutes later and 2ppm 2 hrs later.   I'm planning on trying this a few days to see if the chlorine stays about the same.  Sound right?

Sounds like things are starting to come together for you. GOOD JOB!
Keep testing for a few days more to see if that 1 tsp regimen is the right one. After that you should be good to go.
