Redesigning Sump for 350Gallon (input)

[KingAlee]

Little run down, setup my 350 gallon, had a wet/dry (small) sump… now time for upgrade!

My plan is:

I can’t fit any large enough tanks underneath so I’m going custom. I built (2) acrylic boxes 28” x 16” x 16” and I have a basic 75Gallon. This being said I am placing the 75Gallon in the middle parallel with the tank, on both sides the acrylic boxes will be placed perpendicular to this one. Both will connect to the 75Gallon on both sides via bulkheads and pvc (1.5”). The return will be in the 75Gallon in the middle and I know I want one side to be a fuge and the other acrylic box will be the skimmer, heater, etc.

Now I want all of this within the sump but I also want to add an ATO container, dosing container section, a reactor area and if anything else that you guys think? If nothing else how would yall lay this out? If something else should be added what and how big of a section?

Both acrylic boxes will have filter socks and possibly filter media, so take away the first 6” or so!

The only bulky things I can think of that aren’t already listed would be a chiller, UV, and possibly external return pump(s)!

You can also add a fine perforated plastic grate in one section of the sump if you want to house anything not reef safe in there!

Is there anything that stops you from getting a 6ft 150g tank or something similar to sneak in there? I just know you get a lot more working room when your sump has no unnecessary dividers! — (You could even theoretically break down a few big used glass tanks to go custom depth, with one purchased bottom pane!)

The side compartment only can fit 15.5” is the issue, all the larger tanks I would use are 18”. It has a middle support and it’s a metal stand… very sad I would’ve put a 125 under it!

How much depth do you have? Something less conventional like a fiberglass tank might work well too, giving you sufficient volume without needing the side compartment… that compartment could then be used to house everything else!

Maybe I’m missing something in the layout here… what are the dimensions of the main sump compartment of the cabinet?

It’s not a cabinet, it’s a metal stand that is open underneath, the tank Stan is 7ft by 3ft, the width being 3ft there’s a middle support which is only like 15.5” of open space. That being said a normal 125 wouldn’t be able to slide under it from the side of the tank. Same from the front there is like a 20” gap (I think I haven’t measured it) and I wouldn’t be able to slide the 125 under it there either because it only has 3ft of depth for me to get it under and turn it.

So my best idea would be to slide the 75 in from the front at an angle, make it parallel under the tank and then slide both tanks in perpendicular.

You can kind of see it with the picture attached.

Oof! I see what you mean! Hmm… could you even do two 75g tanks parallel to each-other, and omit one acrylic tank as an equipment area?

Well the 75 would be parallel to the top tank in place where the original sump is, the acrylic boxes would be on each side
