What is your ph

[AussieExoticCorals]

what do you guys set your ph & alk at?

And secondly, how do I lower the ph if is too high?
Thanks

I keep a pH of 8.2 (ocean standard) and a dkH of 9.

 

[bkv1997]

ph 8.2 and a dkh of 8.

I'd do a large water change if it is abnormally high.

[jimmybling31]

mine is 8.2 with dkh 10

 

[oceaninabox]

8.2 with a dkh 10

 

[TROYREEFER]

8.0 for the PH and 9 dkh. If you want to lower your ph a simple water change will do.

 

[CHUBAKAH]

PH 8.3 Alk at 7dkh. I am however running a zeo system which requires a lower dkh.

Vinegar can also drop your PH, but it can cause an algae bloom. Water changes are the best method.

 

[ss7]

8.15 ph @ 7.5 dkh

I pay more attention to dkh and stability of that element rather than chasing ph.

8.4 ph and 10 dkh

I havent dont a probe calibration in a while so I will tonight just to be sure, but my PH has been around 8.4 and reaches to 8.55 during its peak, then drops down to about 8.25 after a couple hours of lights out.....

Do you think 8.55 is too high? I have seen it jump to 8.59 once before

I swing from 8.05 before the lights come on and about 8.2 when the lights are on. My ACjr keeps me honest. lol 10 dkh

 

[blkicebullys]

Ph 8.3 dkh 9

 

[freshfish]

8.3 ph / 10 dkh

 

[jtl2]

8.1 ph and 315meq/l (~8.8 dkH)

 

[jtl2]

should be 3.15meg/l

If your pH is too high, it might be good to look at what might be the cause. pH is a relative measurement of proton concentration in the water, which is affected by different things in a reef.

pH = -log [H+]

Although a pH of somewhere between 7.8 - 8.5 is recommended, where 8.1-8.3 is better, a stable pH is more important than achieving a specific pH, such as 8.2. Better to maintain alkalinity (which changes faster than Ca in a reef), than to target a certain pH.

Does that make sense? :)

 

[TM01]

Ph 8.3-8.55
Dkh 9

I run a Pinpoint monitor and run Kalk 24/7 through my ATO.

 

[aquaman3680]

pH- 8.35-8.4
dKh- 10

I have my kalk on a pH controller!

I don't worry about pH as long as it stable and between 7.8 and 8.5 it will not cause any problems.

alk, I shoot for 10 dKH in my tanks.
