I’m sure this sort of question has been asked a million times so I do apologise in advance but I’m currently in the process of designing a nano aio peninsula tank I have purchased a controllable pump with flow from 300lph to 1200 lph so need to ideally match that The tank is only going to hold 25 litres which means I won’t be using the full output of the pump but would be good should I remove any rock etc and need to turn it up
Question is what size of dimensions should I be looking at to design an overflow vent or would I be better going traditional and using teeth?
I did find somewhere that a 1” (25.4mm)pipe would drain 600gph (roughly 2200lph) so my thinking was a vent style drain 1”x4 inches long may be enough for my needs…Iv never done this before so again I apologise but any advise would be appreciated cheers
