csf On way to respect
Default

I made a 10" cube poly tank. You use a solvent welder. You basically build the tank with lots and lots of tape (masking and electrical) to hold things together and tokeep the sides clean and then you run a bead around all of the internal corners.

At that point the solvent "spreads" to weld the entire seam. But once it gets "wet" don't move it. Check garf (.org I think). They have a tank builder helper for both glass and acrylic tanks. I also didn't use their framing pieces and have had no issues w/ bowing (but it's only a 10" tank).
