SPS checklist? (from your own experience and stories)

[ClubReef]

I personally use the CaCl and Baking soda suppliment that is similar to your current dosing routine. It's definitely doable for SPS and has it's advantages (no pH worries). It also has draw backs in that you have to dose it manually unless you purchase a dosing unit like you have stated. My tank is at a stage where I'm finding that I need to dose more and more every month..I'm at about 220ml of each part daily..this can become a headache especially when you have to prepare the Baking Soda (ie Baking it). Either way Ca Reactor or 2part will work.

If your tank is stable and paramenters in check, you can grow your sps by 1" a month using the 2part method! It also depends on genetics of the SPS, flow and lighting.

Here is a set of growth shots from April of last year to Jan of this year (10K lighting in April and 13K lighting in Jan) using 2part method. These pictures have been cropped to show the subject..but I left the rock in to show asomewhat accurate proportion of the subject.
