Is your Ca reactor not producing enough

I use the reactor to maintain the levels. I use the supplements to get it to the level I want then just use the reactor to maintain the alk/cal at that level.

Also i am going to start changing my ARM media every 3-4 months if I can afford it. I noticed a growth spurt right after I changed the previous 7 month old media.

I measured the levels 5 days ago and found the hardness has gone up to 7dkh, but calcium is still around 300ppm. Megnesium at 1290ppm. I decided to leave that the way it is and have been adding Seachem Advanced Calcium for 4 consecuitive days. My calcium is now at 400ppm. Today I did a 20% water change (haven't done one in a couple months) in hopes that will boost up the hardness a little more to maybe 8-9dkh and leave the rest to the reactor to do. I think part of my problem was not changing the water often enought. I going to test the water again in a week to see if the levels hold, if notk, I will just have to add a Kalkreactor. SPS are darn calcium hogs.
