So with some down time at work I have changed my filtration setup and wanted to get everyones signoff and/or opinions on it.
You dont see it in the illustration but there will be two overflows, one on each end. The overflow boxes will be made from black sheet acrylic and will have a comb style weir at the top and have slots placed in a pattern going down to the bottom. The left side will have one 2" stand pipe, a 1.5" hard plumbed return, and another 1.5" stand pipe for a drain. The right will have a 2" stand pipe and a 1.5" hard plumbed return. The stand pipe on the right side will be fully submerged while the stand pipe on the left will just be a trickle. I will adjust the water volume just high enough to trickle into the higher stand pipe while the other is fully submerged. This should aid in making the overflows as quiet as possible.
Water will travel into the first tank's (55 gallon 4' X 1') mechanical section (still deciding if I want to do a tray with filter floss or use filter socks), then into a refugium. The water will then travel to the next tank (90 gallon 4' X 18"). Water will first enter a fluidized bed (90 liters of MB3 Moving Bed Media from Water Management Technologies. Similar to K1 Kaldness. Here is a link -

Hopefully the diagram below will help explain.
Im not sure if I already posted this but the sumps will sit like this under the tank.
