Hello,
I just did a water change in my reef tank, 25%. I ordered some Reef Crystals, and bot am I sorry! I mixed up the salt saturday, so I could do the change on sunday. I have a 9stage ro/di with ultra violet unit on it. I did the change and my PH dropped to 7.8. I tested some of the new water that I had left.
PH=7.6
Alk-8.4
Ca=420
Mg=1200
Po4=0
I am using the salifert test kits and a pinpoint ph monitor.
