Greetings! I am looking for feedback on my design for a new sump. I am using a 40 gal
breeder to make the sump. My tank is a 125gal reef tank. I have all my parts. I bought 2 HOB
4" filter socks attachments, and a new Mag18 return pump. My design is attached. I am going to use 1/4" glass for the baffles and the space between each baffle is 1". My two concerns on the design are: 1) I would like a larger refugium chamber 2) concerned about the 8.75" return chamber since that is where I will have evaporative loss. Should that be wider?
I have set the baffles at 10" because that is the depth of water that my protein skimmer currently works in. That leaves me with 6" of unused space on top. Do you think that I should go higher with those baffles to get more volume in the sump? I need to accommodate about 11 gals in the event of a power outage.
I appreciate your critique and suggestions!
