I would be nervous about using a buffer in such a small tank- seems like things could quickly get out of whack.
You are correct. Alk
buffers only raise PH temporarily. They should be used primarily to raise Alk
. The PH rise is a side effect that could
come in handy, but is not a means to maintain higher PH levels. Unless you have stoney corals and/or a very high bio-load to use the Alk
, it will eventually climb too high possibly causing many issues from coral death to precipitation. Proper Alk
levels, a mature tank, good gas exchange(no covers, good surface agitation, etc.) and good tank turnover create good PH.
I will keep an eye on it for sure.
PH is highest just before lights out and lowest right before lights on. It would be nice to see it at atleast 8 right before lights out, otherwise it may be getting a little too low at night..
