well considering my PH was at 7.5 during peek lighting and today its at 7.9 im happy. Its not the ideal PH but it is alot better to where i was yesterday. I usually dont chase my PH but when i saw it was that low i had to do something

Your CO2 rate is too high for some reason. I would consider that your circulation in you CA RX is slowed somehow and your CO2 is short circuiting through your reactor. Is you circulation pump clogged? Is the foam pad inside the reactor chamber clogged with fines? Is your media too small? Downflow?? Maybe larger media will get some better contact inside your reactor.
Is your reactor too small for your system?

A secondary chamber on your CA RX would help alot also.

My system PH runs 8.1 to 8.5 all the time with a CA RX and Kalk.

I am using course media in the first chamber and fine in the secon. This actually just started with the PH being so low coming out. I had it at around 6.7 to 6.65 for the longest time. The low PH coming out of my reactor is a recent event trying to keep up with the ALK. I will take it apart tomorrow and check the pump
