Please help! OK I have been putting this off,I have a serious problem with falling PH levels in my pool that has been ongoing for about 8 months or so. The acid pump has been shut off for at least 6 months. I have learned my lesson with leaving the PH at 7.4 to 7.2 having had to recently replace a heater from corrosion.(other problems too).It's been dormant since November to fix the heater. Finding someone to do it here is tough.
Starting the pool back up now, need some help with the long term ORP problems too, this system was quite stable previously.
I have a low level algee problem that I might have to find a new ladder to get rid of (it collects in the struts on the back side and is hard to clean). the ORP drops from 685 to 445 in the 10 hours the pump is off at night.Even when the TA was at 80 it did this. Before the ORP stayed between 650 and 720. Filter is always clean, light bather load.
PH yesturday 7.6 after adding PH up the day before.today 7.3
TA 140 I will start gassing today to bring that down.I use a blower wand on a shop vac tied to the ladder.
CYA 0 indoor pool. it effects the reading on my chemtrol.
calcium never an issue I think it is always steady at 120.
This is as much info as I can give you at this time. Kim
