I have a 90g Oceanic tank sitting here. It was free (thank you craigslist) so I don't have anything to lose by drilling it. But I have never had a RR tank before and I'm not really sure what to do. Not sure how to set it up.
I do not keep SPS corals or leathers/softies in my reefs. Just not interested in those types of corals. I DO keep LPS corals and zoas/polyps with some mushrooms.
I have a 29g tank that would be used as the sump. It's 30l x 12w x 18h. I was planning to section this out into 3 sections. I have attached a crude paint drawing of the plan for the sump/refugium. I like the design, if you see any flaws or reason why it won't work, please speak up.
I want to do a closed loop on this 90g tank because I LOATHE the powerhead look. I want this tank to look clean and professional. I'm thinking 25x - 30x turnover would be about right. My other (smaller) tanks all have about this much flow and it seams to work out. That means I need a 2200 - 2700GPH loop pump.
How many holes do I need for the intake and outlets on the closed loop? I'm thinking (2) bulkheads 2" would probably flow about 2700GPH for the intake to the pump. For the return lines I wanted to use those 3/4" flexible lines so that i can direct return flow, but they only flow about 150GPH, so it's going to take a WHOLE LOTTA them to get 2700GPH back into the tank.
How do ya do this? Do I need to use 1" bulkheads for primary return and only have a couple of the 3/4" flex returns?
Thanks for any help
