PH Drop

MikeyZO · 06-08-2008, 10:35 AM

I thought I read someplace (not sure where) that PH tends to fall at night and then rises again during the day? Is this true? The reason I ask is that my tank has never had a PH drop (and I usually test midday or in the evening and its 8.3) and I tested it this morning before the lights came on and it was 7.8. Now before I go throwing some buffer in there, I just wanna check. Everything seems to be doing fine. Is this a normal occurrence?

Yes, it's normal. No need to add any buffers.
You can reduce the swing if you have a sump by having your sump lighting come on when your tank lighting is off.

Just wanted to add, only if you have a refugium in your sump. If its just a return pump and skimmer in your sump, the lighting won't do anything.

Your alk isn't horrible, but if you're starting to get pH swings you may want to slowly raise it 10dKH.
