Puzzled by water loss over winter

[Bperry]

I cancelled my appointment with the leak detection company. I’ve given it another couple weeks. Seem to be losing a slight amount maybe. My salt level is slightly down and we’ve not used the pool or backwashed the filter. Looks like I may have them come out after all

I used a company here that seemed to do a good job. I think it was American leak detection. Also used another one that found some skimmer leaks early on.
