Equipment for a 120 Build

[mwbeach]

I have decided to move to a 120 gallon tank. 4x2x2. I am in the process of planning it all out.



I currently have a 29 gallon with a HOB skimmer. No sump.



So as I am planning I know I will be having many questions.



Here are a few of my questions to start



1- what size sump? I know the bigger the better. Would a 20 or 29 be enough?



2- what type of return? I was thinking a Mag 9



3- would 2 Chinese LEDs be enough?



4- I am looking at a 20 gallon Refugium. Would this be large enough to be beneficial or do I need more?





Those are a few questions in the planning stages. Any help would be appreciated



Thank you in advance
