How can I turn my old 55 gal into a sump.I want to mimic the ecosystem.How do you make the compartments.Do you use plexiglass?If so How do you cut it?What type of glue?
Is this 55 gallon glass or acrylic? If it's acrylic, go with acyrlic sheets, glued with weld-on. I don't know how to cut these sheets cleanly and usully have the place I but it from cut it to size.
If it's glass, use glass panels siliconed to the sides.
