Dinoflagellates - How to Raise PH

Dyspnea · #1 12-12-2010, 04:47 PM

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?

So I tried the Aquavitro Balance. It does raise the PH but is not very economical as I went through a $13 bottle in a day.

160G total water
My dKH is now at 9.6.
CA = 420
MG = 1400

Before work my PH was 8.1. So I bumped it up with 100 ml of baked baking soda (aka Rndy's 2 part) and 4 cups of limewater (dissolved kalk) to get it to 8.5 before going to work. Came home after work and it was back down at 8.1. This is turning into a full time job. I really don't wanna be driving home on my lunch hour.

Will a kalk drip work to keep it at 8.5 overnight and during the workday?

This is the first time I have played with raising PH and trying to keep it at a consistent 8.5 for a week straight.
Any input would be appreciated.

Thanks

I think that because my alkalinity was around 6.5 to 7, it did not take much to raise my PH in my 75 gallons as I only used one cap per day and it was enough for me, for 4 days.

I really had no trouble keeping it at 8.4 and it was stable with that stuff. Maybe your alkalinity is too high and you have too much buffer to make your PH bulge for long? just guessing here.
