Hi everyone,

I am thinking of trying to make a DIY acrylic sump for my biocube 32G. I am thinking of the dimensions of 17" x 16" [or slightly larger one direction] because this will fit in my sump while allowing room for my Triton element bottles.

I currently use my stand for housing a Reef Angel controller, doser [on a bracket/shelf] and a 5 gallon bucket for topoff water.

I am hoping to use this sump as a large refugium to negate the need for regular water changes [using Triton method].

My question is how large of a skimmer [if any] would/might I need to leave space for in the sump?

I have thought up a 17" long by 4" wide section, cut in half with one side being the drain, and the other side being the return section. The drain side will flow over to a refugium section. If I don't leave room for a skimmer compartment, the refugium could be 12" by 15", or approximately 15 gallon refugium.

If I cut this main section to allow a skimmer section, I might be able to do a 8"x8" section for the skimmer + a top-off reservoir going 4" x 8". This would allow a top off of ~1.5gallons built into the sump as well as a 12" x 9" refugium ~5.5 Gallons

The return section of the sump [at 8" x 4" x 6"] would be around 3/4 of a gallon... I don't know if that's enough water to allow some wiggle room if not topped off within a pretty tight tolerance


I was thinking something like:

Drain level: 14 or 16"
Refugium: 12 or 14"
Skimmer: 8 or 10" [it seems most in-sump skimmers recommend a 6.5-9" range, but I could always put the skimmer on an appropriately sized stand]
Return: 6 or 7"
Top-off section: 12"


I also would prefer to not drill the biocube, and am interested in if anyone knows of some of the more bulletproof methods to overflow without drilling?

I would [for now] plan to keep the false wall on the main tank, and have the return come up and directly to the biocube return nozzle


Any feedback/input would be greatly appreciated!
 
This is what I was thinking, does anyone have any suggestions?

Or does anyone here do acrylic work and want to make some money lol...

I'm located in West Michigan so local would be great (or local source for acrylic with decent prices).
 
As someone who tried to go through all the same stuff, I'm gonna tell ya now -- You will be 1000x happier if you just get a regular tank, drill it, and get a regular sump.

Get a 50/60g cube, you'll be much happier in the long run.

Thanks for the feedback, unfortunately no standard tank sizes will fit in my stand, otherwise that's what I would do
