Hi
I am not sure (i`m confused) how to understand hose seize and equivalent lets say in line heater connection size?
I I am looking in to this http://cgi.ebay.co.uk/Aquarium-Co2-...QQptZUK_Pet_Supplies_Fish?hash=item25574383e5 and i`m using fluval 405 which hose diameter is 17 mm
should I use 16-22, 12-16 or 8-12mm connection sizes?
Thanks
