Can this be done? I have a high PH at 8.45 and want it to go down alittle, however my DKH is at 8.4 and need it to go up. My Alkaline is high and obviously so I wanted to know how to raise my DKH with out raising PH?

:notsure:

It depends what your pH is and why it is low. Sometimes lower pH just has to do with poor gas exchange, eg poor circulation, glass tops, etc.

Just open the nearest window to the tank and leave it open all day. If its raining...thats even better. You will be able to raise it either way from 8.0 to 8.2 pretty easy. Or you can pemantly raise it by adding a light to your sump for about 1 month on a reverse lighting cycle from you tank light. After 1 month...remove the light and you will be pleasently surprised how it will go up permenantly!

Its lunch time
and I will direct you to two resources for the interim. 1 is our very own archives section where there are a lot of discussions on alk, calcium and pH.
The other is google. One of the best resources, IMO, is a guy named Randy Holmes Farley. Use his name and search for things like alkalinity, pH, etc and you may find some good if not overwhleming info!!

Maybe...
pH levels and swings are effected by many things, the balance of Alk, Cal, Mag, Oxygen, photosythesis, time of day tested, ect. My first QUESS would be too much calcium......but could be a combination of these....

Randy has an article titled "An Improved Do-it-Yourself Two-Part Calcium and Alkalinity Supplement System". He states that baking soda may be used to lower or raise pH.
