does anyone know a way to check the flow rate on an ehiem 2236 ecco pro 300!? It's all installed and running and I have cleaned out the media. The thing is I saw it suck up a snail ( from it's shell) as the snail was stuck on the intake pipe. I have checked the piping and can't see a blockage and the flow rate seems ok but I would expect a bit more from a 750 l/hr pump. Should I check the impellor bit in the lid?!
According to the attached short cut: 750lph or 200gph

The other way of checking is to obtain a large container say 10 litre and time how long it take to fill the container. if it take 1 minute to fill - knowing there are 60 mins per hour - 60 x 10 litres = 600 lph of flow per hour, you will probably find that the 750 lph is when the tanister is empty, once the media has been added the flow rate is reduced - to what degree of reduction in flow rate has been induced by add the media - who knows but the avove test will show this.
