which brand CA MG ALK best to SPS?

[Doug]

I use Bens myself but have heard good reviews of BRS stuff also. And both are sponsors here. I remember another sponsor listing bulk supplies also but dont recall off hand.

Other than my Chemmaster supplies I use Seachem products for alkalinity and calcium.

Years back I used both TLF 2-part and B-Ionic 2 part, both with great success. Could get expensive if used for a high demand large tank I imagine. My 70g soft coral tank used 30ml of each per day. Kept alk. @ 9dkh and calcium around 420ppm.

In my current 30g sps tank, I use kalk as the main additive, dripped daily. Plus I add calcium and magnesium to my IO salt mix for water changes, following Ben,s suggested mix.
