I consider myself to be a 'newbie' when it comes to salt. My first coral purchase ever was a Montipora cap. I have had my tank up for roughly 5 months.
The tank is fishless, but I have several substantial colonies of Oculina patagonica, and Caryophyllia smithii. A substantial bio load as they get daily feedings.
The tank is 29g with 40lbs of oolite, 38lbs of LR and soon-to-be sumped with a 29g sump (bit of nitrate issues, HOB chaeto fuge isn't cutting it).
My nitrates have been higher this past week then they have ever been (15 parts from 5 >_<) but my monti is still kicking, although the white line of new growth has shrunk significantly. He has put on 1/4" of growth in the 4weeks I have had it so I must have been doing something right.
I go through 1/4tsp of kalk, 1-2 tbsp of Mg suppliment (seachem), <1tsp of kent superbuffer dKH and 1.6ml of 4% vinegar per week. Everything except the vinegar is on a continuous drip.
I also got a cheep powerhead off amazon, 3000 l/h 110volt. May be a bit much lol.
A word about the DSB. All the literature I have read says having one is a good thing (3" or deeper with sugar grain sand); in theory, organic buildup shouldn't be an issue(to an extent) if you have adequate micro fauna.
Also, don't underestimate the importance of flow. Avoid getting 1 big powerhead and hooking it up to a timer (like i did) and expecting it to do a good job and not run backwards (only a matter of time before it runs backwards).
