Water changes and might want to monitor that reactor a little more closely.

Are you also supplementing?

[Redrover]

Water Changes done weekly 15 percent
All parameters are right on the mark
I have been told by a sixteen year reefer to shut the Co/2 off
It has droped from 580 to 540 in 4 days
No supplements added

-580 ppm wow, and I thought my 460 was high!

Check the tank pH and the Alk level. I bet your Alk is low.

Ph runs between 8.1 / 8.3
Will check my alk in the am...KH 110
Thanks: RJ
