40g breeder sump/refugium

PhilMStudy · May 31, 2021

Hello, I’m not really looking for additional mechanical filtration as much as I am a rubble rock and macro algae pod farm that also helps with nutrient export, incorporating a rdsb as well

would I still need baffles and what not or could I just plumb it and let flow do the rest of the work?

also, any tips for a good overflow box and size to look for? This is a first for me

I have my 40B sump set up for this type of application. First chamber is full of rock rubble, large fuge, then return. My baffles are as follows left to right.
I put an egg crate rack in the rock chamber to aid in flow and keep rock off the bottom.
1 full baffle raised 1.5 inches off bottom
1 baffle 2 inches away that is 4 inches (roughly) tall.
1 baffle that goes from the bottom to form a weir
1 baffle 2 inches away that is raised 1.5 inches from the bottom.

I’m looking at overflow boxes, 75g DT, 40g breed sump/fuge, figure I’ll push 80-90 gallons of actual water...

cpr vs e-shopp seems like my choice, tips? Also, would an 800gph pump be enough?

Would .220 acrylic work for the baffles or should I look for thicker material?

I’m going to be building it this weekend

getting a life reef single/standard overflow box, already have tank and getting acrylic today or tomorrow AM.
