You put so much doubt in my mind I have to go a check the pump. It’s rated at 2500lph with a max head of 2.5m so I'm thinking I might get 300-600lph flow through the Fuge witch I believe to be ideal! Thanks again for all the help with this project, good to have fresh eyes at it as I've been planning so long sometimes I don't see the obvious potential faults.
Still working on the light rack, switching consol and the full system sketch-up diagram. Will keep the thread up-to-date so much as possible..
