My stance on Mg comes from 8 years running a tank where the acros grew too fast. I never added anything, and nobody I know did either. The whole Mg trend has been the last couple of years, and while it may not be bad, it's never been needed before. That being said, I've had it tested several times and it's always near 1400.

I'll dig up an old photo to show what I used to get, doing the same thing I do now...

Here is an old pic of my last setup, this is the type of growth I got in 2 years. Not anything like I see now. And really not doing anything different, feeding, Mg, etc...

That looks great! Do you think the sand bed had something to do with it or the city has added something to the water supply?
