I was gifted a 300 gallon acrylic aquarium 96Lx 30Hx 24D with two inside corner overflow boxes 5"x 5". I wanted to run the bean animal system. I noticed that all three pipes are normally all plumbed in the same overflow box. what would be the best way to run the bean system on this tank. the two 5x5 overflows will only fit one 2" or one 1 1/2 pvc per box unless i drill the side of the overflow boxes and mount the remaining pipes on the side of the overflow. i was thinking of just buying a synergy V3 16" shadow and mounting on the back center wall giving me the bean animal system and using the two interior boxes for 1" returns or something else. I ran a 300 gallon glass FOWLR tank in the late 80s with two 2" drains, one in each overflow box. it was super loud. my priority is silence, emergency drains, and 2500-3500 gpm on my return. my aquarium is blacked out on the back and sides and im able to drill the back and sides of the aquarium if necessary. I have about four feet of room on the sides and back of the aquarium. i will be running a FOWLR tank for the first year or two before switching to Reef to get my tank established and to get caught up on all the forums. ive been out 35 years and getting caught up wth all the new methods, Herbie/Beananimal. I would appreciate all your different ideas and opinions. thank you
