Is there anything at all you can use for low end calibration fluid for a PH probe? I have the high end (10.00). No one has the 7.00 an the quickest I can get it delivered is a week or more.

To calibrate a marine PH meter you calibrate for the high end. You use two, 7.0 and 10.0.
Low end would 4.0 and 7.0.
If you go to bulk reef supply website they sell them all 4.0, 7.0, and 10.0.

If you pay for upgraded shipping, $5.00, you can get it a lot faster.
