Hi guys, I’ve just bought a 6 ft tank 670 litres, it is around 4.5 foot off the ground (including cabinet) I have chosen to use an external canister filter but so far I’ve had a nightmare finding one that will work. I have a fluval 406 that will only work if it is elevated, I have a tetra and an airpond one and they are the same. I’ve just connected a pump to the inlet to try and assist the process but it doesn’t seem to have had much of an impact as the water is coming out at around 50% of what it should be :-( any tips would be greatly appreciated as I’m at a loss with what to do. Thanks
