Dinoflagellates - How to Raise PH

[Dyspnea]

I battled low Ph (like 7.9 or lower) for quite awhile I always felt I had excellent water flow/oxygenation, and a low bio load. So I looked at other causes like my calcium reactor, water quality, etc. Nothing I did fixed the problem, and adding chemicals to the water is only usually a temporary solution.

Anyways what solved my problem was just using a small air pump with a wooden airstone in my sump and it drastically raised by ph to 8.5 over the course of several days.

So look at your water flow/ oxygenation.

How often and much of a water change are you doing? I find that if I keep up with water changes ph remains stable for me.

However an air stone produce a lot of salt splash and salt creep everywhere when the little bubbles burst. Very messy. Obviously your low PH was caused by lack of aeration.

Salt creep was very minimal with adding the air stone, I was just suggesting he consider waterflow/oxygenation as a possible cause.

Airation is not a problem in my tank with a large skimmer and 2 MP40's causing lots of surface agitation.

I will look for the Aquavitro - Balance.

Sunday morning parameters:

PH = 8.07 (8.31 at lights out last night)
Salinity - 1.024 (down from 1.026)
Alkalinity - up to 8.8 dKH (8.0 yesterday)
Ca/Mg didn't measure today

Any other suggestions?

Still can't seem to raise my PH to 8.5 with just saturated kalk. Problem is my salinity is dropping to low. The evaporation rate is not enough to match the kalk top-off water I am adding via a 4 cup addition every hour.

Why don't you use the HO balance? it is very fast and easy to raise the PH with the stuff and I had absolutely no adverse effect with it on any of my sensitive coral and SPS.

Danielle - What size is your tank? I have 160 G. Is this stuff potent enough to raise the PH of 160G economically?
