View Full Version : Lowering Calcium and KH

11/20/2008, 12:57 PM
I have setup a calcium reactor on my system, to try to keep SPS.
I have made the mistake of running the reactor for too long each day.
I only noticed this when some of the SPS polyps didn't come out.

Upon checking the water params are as follows:
KH is now 16 (5.71 meq/l)
CA is now 520
MG is now 1350
PO4 is now 0.01
NO3 is now <5

I have done two large water changes (20%) and the params above are as they are now (ie. after the water changes).

Does anyone have any hints or tips on how I can reduce the KH and CA?

Just leave the reactor offline for a while and let it naturally fall. do more water changes in attempts to dilute it, but there's no need to drop it quickly or add something to bind it up. Let it occur on its own.
