Hey folks, been awhile since I've been on this forum. I recently set up a new 180 gallon in wall mixed reef tank with a 100 gallon sump. The sump is located in its own room which houses two other tanks. I'm considering adding a third tank to my reef system in the back room. I'd like to add a 40B RR or drilled tank that will utilize the same sump as my 180 gallon. I have a few questions.
1. The nem tank will have some live rock but not enough for itself. Since the system is going to have the same water should I wait for the 40 to colonize with bacteria or can I just add water to it and go?
2. I plan on collecting some different color BTAs for the tank. Lighting. Will I need MH/LED? Or will CFL/T5 work. I run halides on my reef but it is 24" deep.
3. Flow. I hear that nems need around 10x flow. So I'll need minimum of a 400gph return pump on the additional tank minus head lift. How high SHOULD I go?
