What Calibration Fluid can I use?

[reefs4life]

Hi everyone I just bought a neptune AC3 and I finished setting it all up today but I need to calibrate the pH probe. I looked up the Neptune calibration fluids and only found the pH 10 fluid. Now what can I do? Can I use calibration fluid of any brand? Thanks in advance for the help. Thanks, Fortunato

Brand does not matter as long it's between 4.0 and 10.0.Try Saltwatercritter.com or eBay.

Don't I need 7 and 10 though?

7 and 10 if you are checking ph above 7
only use 4 if testing below 7
most people on use 4 for calcuim reactors

So when I'm setting it up and it says to calibrate for pH 7 I use the pH 4 and then when it says to calibrate for pH 10 I use pH 7? Or does the AC3 have option to specifically calibrate for 4 and 7, because I didn't see the 4.

No you need to get the right solution 7 and 10 only
