Return Pump Set Up

[Herrwibi]

I'm looking at starting a project on my 15 gallon tank doing a submerged trickle tower filter .

Obviously the return pump is going to be around 200 gph .Taking the height etc to try and turn the tank over 10 times .

My question is most of the pumps I can find only have a nozzle of 11/12mm . What kind of pipe work or fitting could I get to transfer it from 12mm hose to 16mm as I can get 16mm pvc pipe .

Given your use of metric system I assume your are not in the USA. I have bought lots of fixtures and adapters from flexpvc.com ... maybe you can find something similar in your country?
