I recently salvaged two pieces of 3' clear pipe and would like to use one as a kalk top off reservoir (similar to Tunze kalk reactor). ID of the pipe is 3" and OD is 4.5". I'm not sure what material it is... could be clear PVC or it could be acrylic. So, what should I use to bond PVC end pieces to this pipe. I'm thinking some type of weldon but which one and where can I purchase it?
Any help is appreciated.
