raising PH

[steve bergmann]

I was able to raise my Ph on my tank from 7.8 to 8.4 by raising my return tubes to 1 inch out of the water creating oxygen and dosing Kalkwasser at night. Here is a current video of my tank:

More aeration as you got with changing the return can raise or lower pH, and may do both during the course of one 24 h period. Whether it raises or lowers pH depends on the alk, tank pH, and the ambient CO2 level of the air.

Kalk, of course, is a good way to supplement alk with a nice pH boost.

The raising the return lines seemed to give me a .2 boost going from 7.8 to 8.0 pretty consistent. I kept alk at 8.5 at that time and calcium was at 430. Adding the Kalkwasser actually lowered my Alk as I basically reduced dosing Soda Ash and a little of my Calcium to keep my Alk at 8.0. Now Alk fluctuates from 7.80 to 8.05.

I dose Soda Ash during the lighting periods and switch to Kalkwasser at night. I am hoping to try to keep the PH more stable this way while also trying to keep Alk more stable as well.

Randy always glad to hear your thoughts!!!!!!!
