I've been slowly working on getting my Alk higher...when i started my testing I was always around 6 and my PH was reading around 8.08 at night to 8.4 at end of light cylce.
Now that my Alk is up at the 7.8-8.0 range my PH is 8.18 or so at night and peaking at 8.58-8.6 during the day...that seems dangerously high according to what I've read. (the higher my Alk gets the higher the PH swing gets)
The only thing that I can think is that during the day I'm low on carbon dioxide in the tank. My gas exchange should be good...I am running a skimmer and get good agitation at the surface w/ my spinstreams.
So what does one does to raise Alk and Lower PH? Right now the 2 part I add (seachem reef fusion) to keep my Alk up also raises my PH. I does in the morning when my PH is around 8.18 or so - not at night when it is sitting high.
I currently don't test for Mag, but my calcium is at 400.
I am not trying to chase PH, i'm just concerned that it is getting way high...i've read a few places that a swing of .5 is normal in some tanks. Just i wasi the swing was from 8.0 to 8.4 not from 8.18 to 8.6.
I was thinking maybe more fish in the tank to create more carbon dioxide during day. Just don't want to add to many fish since i just have a 16 gallon...trying not to overdo the bioload. Currently have a 2.5" clown / 3.0" clown / 2.0" Tailspot blenny.
Thoughts?
