I had planned this year to build a large plywood tank, I may still go that way but firstly I would like to at least get a few quotes from some acrylic tank manufacturers. I've got a few numbers to ring but i'll be going into them blind, not knowing anything about the people i'll be ringing. I'd prefer to ring companies who at least have come recommended by hobbyists who've actually had dealings with them and can vouch for their service and reliability. Can any UK hobbyists point me in the right direction?
