PH Issue

[Alex T.]

I'm having a hard time keeping my PH above 8.15

Since my sps and clams seemed to kick into overdrive a few months back, my reactor was adjusted to keep up with demand, and I drip kalkwasser too. The tank has always hovered between 8.1 - 8.3. Now, it will dip to 7.95 with a high of 8.15

Any ideas on what I can do to get it back in that range?

It's fine in that range - but you could try simply opening a window in the room where the tank is to get it up a bit.

i agree that range is perfectlly fine for sw. the window idea is good. what I used to do is run my airline from my skimmer out the window and pit some carbon on the end so nothing from outside would enter through the airline and that raised my pH back up.

Your pH range is fine, but you can also consider chaeto macroalgae in the sump on a reverse daylight cycle, if you haven't already.
