pH dropping -hello winter

I generally treat pH as an entertainment value, and something to ignore unless something looks really wrong in the tank. Mine drops down about .2 in the winter. As long as your corals are healthy, I'd recommend ignoring it and just enjoy the tank instead of the Apex!

As a relative newb I am going to continue to monitor my pH levels as a possible early indicator of something going horribly wrong. A pH probe and the occasional addition of buffer isn't going to kill me.

Once I become an expert like others here I'll know when I can ignore it

I have had some terrible PH issues in the last few months. I can't get it to go up. I'm dosing almost 5liters of saturated kalk per day. My Alk was crazy low before and now appears to be closer to normal, but I can't get PH up. Best it gets when lights are on full is 8.05 on my APEX. I've got two probes in different locations as a backup check. It is an issue for me as having the PH and Alk so low resulted in some cyano issues. Still trying to beat that too. I also have an HRV feeding fresh air only 10 feet from the tank. Not sure where else to go with it.

That's interesting, I didn't know that pH and Alk had an affect on cyano. I'll have to go read up on that. Myself, have had cyano in my tank during the summer with High pH, 8.1 and above, as well as in the winter with low pH, below 8.0.

Alk seems to be the culprit that more people are comfortable associating with Cyano...though many threads have said raising PH has helped them rid cyano from tank.

MB7 is what keeps my tank clear of cyano. Learned that a couple years ago, and have not had a problem since.
