about to set up new 250-275 litre tank. if i use existing externals true flow would be approx 2300 litres (rather than 3850 the manufactures claim). is this amount of circulation too much for a planted tank? thanks
But isn't there an issue with fish? Even with a spray bar my peacock gobies don't like it if I face the flow directly into the tank – from a Fluvial 107 – and it creates conflicts over territories, as the fish retreat to quieter waters. In another tank I have some small habrosus Cory and they struggle if the flow from an Eheim pick up isn't baffled. It's something that confuses me, how to have a good enough flow to limit algae and spread oxygen, while not blowing the fish away. I am sure that's down to my own inexperience.I have a 100 litre tank with 2600l/hr total published flow from my 2x canister filters with Lily Pipes and 1x usb pump (at substrate level). None of my plants appear 'harmed' by the flow.
Heres a thread on high flow rates: Filter experiment to control algae
