Ph probe storage

[Arcu2]

I’m taking a tank down and was wondering how long I can keep my ph probe in a cup of saltwater until I get a chance to buy the probe storage bottles with solution. Is it fine in a cup for a week or 2?

Keep them wet is all you have to do

Yes.

Don't store them in RO/DI or full strength seawater. Diluting seawater 1:1 with RO/DI is a good middle ground, short of buying a storage solution.

Reason: you do not want CaCO3 precipitating on the glass bulb, nor do you want RO/DI stripping ions from the glass bulb

The diluted suggestion should be good. If you want to be sure, BRS sells PH probe storage solution but it seems expensive for what you need.

Lol. So monitor the pH of the saltwater your storing it in, for the week or two it’s out of your tank.

Salt water is fine, just dont use RO or distilled water.

For longer term you can use ph4 buffer for storage.

Storage solution is just 3M KCl which is easy to DIY (cheap too)

I agree but on short term storage only

Guess I should quit storing my pH probe in my DT to take measurements
