Plumbing, A few new Questions

[spoot]

Not sure how many food grade clear plastic containers you can find, especially ones that hold water. You could try some sort of weld-on to attach the baffles. But the fit isn't going to be that great unless you cut it very carefully; the plastic tubs are all weird shaped.

If you have the money, time and skill, consider getting some glass cut and siliconing yourself a sump. It would be the exact dimensions you need and you could do all the baffles at the same time.
