Hi all,
quick question: my 65g mixed reef has been going strong with baseline pH around 8.1, dkh 7-8. I started a gravity kalk drip 2 weeks ago-- was bumping pH and alk a tad. Yesterday I mixed new batch (weekly) and turned the drip up a bit. Came home and not surprised to see pH on the meter read 8.14 (calibrated 2 days ago). However when I tested with new Red Sea pH/kalk I was very surprised to see pH 8.4 and dKh 14!! I checked with my API and found pH 8.3ish and dKh 12.
I turned off the kalk and figured I'd restart at a much slower drip tomorrow.
1) do you think this high of a dKH is stress level high or ok?
2) not sure what to make of this pH meter- reads ok when I calibrate but doesn't even come close to what I'm getting with API and Red Sea.. frustrating. Guess I should stick with the test kits?
Suggestions?
thanks in advance.
Brad
