Hello Everyone,
I’m new here with a brand new 3 week old pool. I have read all the
old posts and I know I found a wonderful resourse with great people in
this group.
I have an inground 20 x 40 gunite pool with a DE filter and a polaris
crawling around it 3 hours a day. Right now I am getting it serviced
weekly but after next week I am getting it serviced every 2 weeks with
the idea (ha) that I will know what to do during the time periods its
not being serviced.
1. PH - My PH had been constantly high and I was told this was normal
due to new plaster. On Friday the service guy put acid in the pool.
Saturday morning and Sunday morning (today) the PH tested low. Should
I do anything or will it naturally come up since its new plaster? If
something should done, what exactly is needed? I’m clueless about
pools.
2. DE Filter Pressure - I was told the pressure should be between 15
and 25 and to backwash when it goes over 25. Well, the pool was
backwashed on Friday and on Saturday when the filter turned on in the
morning (its on from 8 am to 8 pm) the pressure was at 19. But by 4
pm it was on 30. It can’t possibly need backwashing this fast? I
know the longer the filter is on the higher the pressure gets, its
always lowest in the morning. But I guess I’m a bit confused, is
something broken or is this normal? And if its normal how do I know
when to backwash?
Thanks all in advance for your input.
Debbie

Just to add one thing about pH and heaters — the temp sensor for my
heater (Aquacal heat pump) sits inside a thermal well which I *think*
is made of copper or brass. Anyway, last year my pH was running
steadily high, and I was too lazy to keep it corrected. Late in the
summer, water started shooting out the top of my heater because the
high pH water had corroded the thermal well. It doesn’t take much to
eat through this!
As to the general chemical discussion, I went through a lot of
chemicals my first year because my pool company did not tell me about
stabilizer. I now make sure that the cyanuric is at the correct
level, and I use much, much less other chemicals. I also believe that
regular use of a solar blanket reduces the dissipation of chemicals.
