KH out of whak?

[kenettson1]

Ca @ 410
Mg @ 1100
dKH @ 12.8?

dKH too high?
How do I lower? I've done several water changes over the last few weeks... about 2 10 gal changes.

Been dosing Mg to get it @ 1300-1500
Just started Ca reactor ... been running one week.

I was using 2 part dosing method before I started using the reactor.

Oh yeah, I tested it with Salifert KH test kit 3 times in the last 24 hours to make sure it was correct.

The alkalinity is OK, but I might let it drop a bit. I usually recommend 7-11 dKH. If it is stable there, just add a little less CO2 and it should stabilize at a lower value. No need for water changes.
