I would like to build a sump and refug out of a 31 or 40 gal rubbermaid tote and place it under my tank in the stand. The tank is not drilled but is plastic so I plan on installing 2 overflows.

I have a series of questions:

1. Is it realistic to make a combined sump and refugium?

2. Realistically, how much water am I going to be able to add to my system with a 31 gal container? Would it be worth going with the 40gal?

3. Should it be clear? I think it would help to see the water levels etc but is it necessary? Would it be different if it were a sump only?

4. Since I can't glue dividers to the side walls, how do you make baffles? Or can you glue them if you make a wood "girdle" for the rubbermaid?

5. I was thinking about a submersible pump but will it take too much water "space"?

6. I currently have a remora HOB skimmer. Can you put the HOB in the sump or should it hang on the back as designed?

7. The overflows come in different sizes. Do I match the overflow with the pump size?

I f you have any pictures of rubbermaid sumps I would like to see them if possible.

Thanks for your reply,

I am interesed in the refugium for nutrient export and for pod growth.

The sump is desired for many of the reasons mentioned on melevs site, constant supply of water in display place to put the sutff and place to add stuff to the water (kalk atc.)

thanks.

If you're looking for nutrient export then you want to keep macros, and also provide a safe haven for your pods to propatate. You don't necessarily need sand in your fuge unless you also are looking for denitrification. As far as the pods go, you can add some live rock rubble in piles for them. The thread I have linked is outstanding, IMO. Lots of good information there:
