I had to go out of town for a week, so I put the floater back in. I came back and my test kit had arrived and here is what I found:
pH - ~8.0 (I did this twice to confirm, it was nearly as pink as the 8.2 window)
FC - 18
CC - .5
TC - 18.5
CH - 425
TA - 150
CYA - 160 (using diluted method)
Pool was exceptionally dirty and I brushed it before doing these tests. Not sure if would effect, but wanted to mention.
On my filter, the pressure gauge apparently does not work (stays at 20PSI when pump turned off). The OEM replacement is $27 on Amazon. Will any 0-60PSI gauge from Home Depot or similar be sufficient? Leslie's Pool has a one for $11, but not well-reviewed. Also, how do I release the pressure before changing the gauge? In the videos I watched there was a push-button to release pressure which this unit does not have.
On my pool pump timer(Intermatic 104R), the clock gears turn, but the clock face does not. Should I simply put in a new clock unit ($54 at Home Depot) or is it possible to clean out the gear assembly to get it moving again?
Also, the pool pump runs very hot (casing is 140-145 degrees). Is that normal? Or is that something that I should have looked at?
My current plans are to get the pool pump timer working and the pressure gauge replaced then backflush the system so I have a baseline pressure reading. Will wait for expert advice on what do with my test results.
Edit: Changed TA from 15 to 150
Edit: Updated CYA numbers after doing diluted test
