What method/test kit/probe are you using to test your parameters?

tat's weird...very weird...i thought the higher the kh...the more stable should be the PH 8O ?can someone verify that?

Generally, but this problem is not unheard of. I suggest searching our library, http://www.reefs.org/library, as well as the Advanced Aquarist database. Also, do a search on http://www.wetwebmedia.com on pH, dKH, KH, and alkalinity. I know for a fact we've had more than one or two queries come through very much like this.

Whats your calcium at?

How are you testing? PH Probe, check the batteries and recalibrate it.

Double check the test kits with another one.

This article hepled me get all my parameters in check.
