Does anyone know a good source of acrylic to make an overflow box?

why not glass?

trademe, people always selling offcuts on there

Briananemone - Go into a plastic fabricator. there will be dozens around, people who work with plastic to make signs, stationary holders etc. Go in with your measurements, and they will cut it to size, be surprised if it costs $10.00 if the can find it in an off-cut.

One of the places down here had shelfs and shelfs of offcuts, I think I did them a favor by taking some away

My overflow cost $15, the plastic (blue), cut to size, cut in half, bent and 90 degrees, with 3 extra bent strips and they even threw in some glue in case I needed to glue some together. Awesome. Laser cutting cost an extra $60 I think, but had to be done at a different place. worth it I feel, as it just looks tidy compared to DIY (which I have on my other tank

hi brain i got some clear u can have just let me know

cool, should be interesting making the overflow, for my brothers tank he didnt want a sump untill he realised that a venturi makes a noise.

Theres a perspex place in AK on the hill between TVNZ and vic park markets. (cant rem. the name) They have offcuts which they practically give away. I got a couple of 300x400mm x 5mm thick for a couple of bucks not long ago.
