I have 200 litre tank with 3 electric blue acara 1blue acara 2 angelfish 2 clown loach 1 green phantom 1 bristlenose with a fluval 406 currently filtering with around 1400lph if I added a fluval 306 with around 1100lph would this be to much flow in the aquarium?
I think you could still put them both on but you would just have to set up some good spray bars to keep the current low. I'm not sure if it's completely necessary though.
