Crazy Idea: Extruded Polystyrene Sump???

[jbolinger]

I have some pieces of 1" extruded polystyrene left over from my abandoned DIY 3d background attempt.

Would it be sturdy enough to make a sump? Perhaps 10 or 15 gallons?

How would I seal the joints? What about coating the inside with epoxy resin?

Yes, I could buy a 10 gallon tank for under $10, but since I already have the polystyrene and epoxy it is 'free' .

Or am I completly bonkers with this one?

As my Daddy used to say, "Some things are just too much trouble for a nickel," . I'm sure it would work, but unless you've just really got a lot of time on your hands and nothing better to do, I doubt it would be worth the time and trouble you spend on it.

I think thats what I used to line (insulate) my sump. I cant amagine its rigid enough to make a tank out of though? Were talking about the blue foam right (not really sure I am at work right now and not lookin at the stuff)?

I'm with everyone else, even though it's a worthy idea it's too much trouble. You have to think of heated water, the flow that could knock things around, the sealent wouldn't be as strong on such a "soft" material. Although, you could place a piece over a sump to give added insulation so that the water will not loose as much heat during transfer. Or you could sell some fish and use that as packing material, or as cushion for a tank...whatever you do with it however, don't try to use it to hold water...
