PH, how can I get it up?

My lights are about to turn off and my ph reading is 7.97. I beleive it should be 8.3. how can I raise the ph without a ph buffer? I have a ph buffer but it also raises my alk and my alk is high already. any suggestions would be great at this point. thank you

 

i use wardleys ph up if its low but i'm not sure if its the correct thing for you.

 

It it low P.H from lack of Carbonates or excess of CO'2 ? whats the DKH of the water .. If you need to increase the carbonate or DKH level then a good reef buffer is all you need to add . But if it is simply a increase of CO'2 then you can just get some Arm and Hammer washing soda at the grocery store and add 2 Tbls per 100 gallons of tank water to a glass of R/O water and stir it and pour into the tank this will increase the P.H and not mess with the carbonate level. I'd look to the low DKH levels first unless you are using glass tops on this tank..

 

Water change with Kalkwasser as kalk has a pH reading of around 12! Their is a pH buffer that has no effect on alkalinity!!!! Put out by Salifert!

 

Hey tangster and everybody, here are my levels;
dkh...13.2
alk...4.69
phos...0
cal...360
mag...1200
ph...8.0
amm...0
nitrate...0
nitrite...0
so what do you think.

 

I take it you are using a PH monitor? or test kits?
do you have a cover over your tank?

Hi Jason, my tank has no cover whats so ever, open top. I do have a ph monitor and test kits. why?

 

A lot of PH problem can stem from improper gas exchange and thought if you had a glass top that could have attributed to the reason (But no).

Does you PH monitor agree with your Test Kit? Have you calibrated your PM monitor?

J

 

yes the monitor has been calibrated. I dont use the ph tester anymore b/c I have the monitor, having said that, my ph tester isnt the number result, its the color one.

 

Dissolved oxygen and carbon dioxide in the pelagic areas of your tank will add to your pH reading as will excess food just to mention a few components of pH fluxuating up or down!
