If there is anyone in the UK that has made this reactor I would appreciate some input on where to get some of the the parts from.

The ones I can't find are:

2" Clear PVC housing
2" slip to 1/2 threaded bushing


Thanks, Matt

PS - I have been using the Barr internal reactor for over a year in my tank and am really pleased with it. Thanks Tom! Am only changing over to this design as I am moving all hardware outside of the tank where possible.
