pH cycle...too high?

Its a two stage reactor, so it probably isn't affecting the tank as much as might be expected....and I'm only running the reactor at 6.8.

My Ca/Alk demand is such that I could turn the reactor up....based on the current pH, I think I'll drop the reactor pH a bit and see if that causes any affect upon it.

There is a good chance that the 48" x 72" surface area, as well as two sumps (18" x 36" & 24" x 48") might be contributing to better-than-usual gas exchange.

I also think that I can see the effect of glas cleaning in the daily fluctuation. When the glas is cleaned, the cycle is slightly lower. As the glas greens up, the cycle gets higher.

Like Tony said, I wouldn't worry about it. Many reef environments reach 8.8 for pH. If things look great, and your not having any problems I wouldn't panic.

my ph is always between 8.3 and 8.7 - 8.8.

Thanks...that makes me feel a lot better.

My pH problems went away when I tossed my meter out...

I solved the same problem by not calibrating the probe forever. Then when I did get around to it (last night). I somehow got water inside the case and capooooow. My ph is now 88.88!!!

On a lighter note, I have never really been to concerned about what my ph is at or fluctuating to. What I do notice is when fluctuations are increasing in differance my alk is ussually getting on the low side.

What`s your tanks alk ?
