Long timer reader, first time poster. Thanks for all the info so far.
Converting to salt:
I thought my pool was 25K gallons or so, based on previous chemical effects
Aquacheck strip said 500 to start.
I added 15 40# bags.
Aquacheck strip said 4430!
That would make my pool 18.5K gallons. I must have done the test wrong, but hard to screw up a strip test like that.
Pool store says 3400, Cell says 2600.
I turn it on and diagnostics say 26.27V 6A 83F 2600PPM.
It then shuts itself off saying low-salt.
I had previously cleaned the cell using a water hose to get various chunks out and yesterday I did a 4:1 water/muratic acid soak.
This is a used cell I bought from a pool builder switching to some "natural" system. I also got the rest of my automation stuff from her at a very reasonable price. I don't think she sold me a busted cell, but it did sit on my deck for 6 months while I did other pool improvements.
I'm taking the cell into the pool store today to have it checked. Is there anything else I should do?
The rest of my chemistry is pretty good.
