Where to get pH calibration solutions?

[Mamejunkie]

I have 2 used Milwaukee pH meter and need pH calibration solution to set them up. Believe they use 4.01, 7.01 & 10.01 pH solutions to calibrate. It doesn't seem to be a common item so hard to find. Anywhere local you know of? MarineDepot doesn't carry it.

We have a couple boxes of 4.00, 7.00 and 10.00 instock, this is from neptune.

Not really local to you but anyone in the SF valley looking I know Rainbow Pet keeps 7.0 & 10.0 in stock.

You can use the Pinpoint packets. Most good LFS will have them. Most probes use a two point calibration, if that's the case use 7.0 & 10.0 for SW.

I wouldn't worry about the .01 suffix or the brand for pH solution.

Amazing Aquariums & Reefs, SoCal tropical, Marine Depot, Tongs should all have it. Usually 1.00 - 1.50 p/ packet.

Thanks for the info reef_doug. So does it mean I don't need the 4 pH solution?

Yes. Most SW tanks pH range between 7.8 and 8.2 so the 7 & 10 are what you want. The 4 & 7 are for FW.

The 4 can be used for ORP, but that's not your situation.
