That is correct regarding the ORP sensor. Oh well, I guess we will keep adding sodium bicarb to raise the alkalinity. Does this have a negative effect on the equipment though or other negative effects to be concerned about?

I tried this for a few hours yesterday. The jets were turned on twice during that period which caused the pH to go from 7.2 to way off the charts (my guess around 9.0 from the color difference but hard to say). This somehow also caused the system to read the chlorine as critically low and the...

I'll try that and see what happens.

Looks similar. I can't find a test kit labeled like mine online, weirdly. Thanks for the testing pointers; I'll try that out. Yes, it has automated pH system. I wondered that myself, if the system might be overcorrecting for a higher pH.

It says Item #57086 Complete (FAS-DPD chlorine). The test procedure is to 1) add 2 drops R-0007 (thinosulfate) to a 25mL sample and swirl to mix 2) add 5 drops R-0008 (Total alkalinity indicator) to the sample and swirl to mix 3) then add R-0009 (sulfuric acid) dropwise until the sample color...

There is no issue testing the water for the main pool though. Only the spa has this issue.

It is a taylor test kit. We recently replaced any expired testing chemicals so I know they are up to date.

I recently (a few months ago) started assisting with pool operations at a small hotel. The person I assist told me that we have to add total alkalinity every morning to bring the levels up since the drop every day. For example, if I add bicarb in the morning and bring the level up to 80ppm (the...
