anyone out there growing sps in there nanos

hey guys i have a 30gal reef that i'm trying to grow stoney corals in, is anyone growing sps coral (acropora) in there nano tanks and if so what are you using to keep your Cal, Kh and ph just right.

Yes - using litermeter 3 for kalk top off + b-ionic dosing.

I dont worry about pH too much. It swings from 7.9 - 8.4 daily. But the top off / dosing keeps my kH spot on.

i don't have sump or an autotop off, is there an ideal one part dose that would be just as good?
