Cool, sounds like you got it going now. I didn't really know mag would effect growth that much, but from what you are saying it seems like it does. What test kit do you use to test for mag?
I drip kalkwasser, but really hate mixing it and everything. So I want to order a 2 part as they call it on BRS, but it actually has the alk/cal/mag and I will manually dose it until I get a handle on what needs to be dosed daily. Then I'm going to get a dosing pump that will dose all three solutions out of the bottles. I figured out how much evaporation I get everyday and I'm going to hook my my ATO system to keep the water level in my sump stable. So I'm slowly working at getting the tank automated. One thing I've learned from reading a bunch of post is Keep Things Stable for the best success.
I use only Salifert for my test kits.
Look into a reactor, its almost set and forget once you get the right amount of kalk in it. Makes a world of a difference. Mine is dosing for 2 minutes every 11 minutes or something like that.
