Standard first tests for unknown pool history?

[mikebw22]

If I am going to maintain another pool that I don't know the history of or what's been put into it, what first tests
should I do to start out with? Just basic tests or more?

Thanks

Test everything: FC, CC, pH, TA, CH and CYA ... otherwise you have no idea what you are starting with.

Would you also include tests for Potassium monopersulfate, borax, copper etc.?

Thanks

I suppose it would not hurt if you have the tests available ...

I guess I was coming at this like a residential owner, maybe you are thinking more of a business venture where it might be worthwhile to cover everything so that problems do not develop unexpectedly (like metal staining starting, etc)

Well, just friends pools for now. I think I've maintained my saltwater pool pretty well for the past 4 years. Managed to keep the 2003 Autopilot control working even though the early ones have issues, bad capacitors, running hot etc. I don't have a cage so it is a little more maintenance and testing.
But yes, If I am going to look after other pools I don't want to overlook something that would cause problems down the road.
Guess that comes from being a long time mechanic.

I would test for borates, copper, iron and salt besides the normal tests. Just to cover the bases. I wouldn't worry about the MPS test unless you have reasong to believe (i.e. MPS container) they've been using it.

If the water source is different than yours, I'd check the fill water as well just to have a reference point.
