I have a 55gal planted tank with xp3 spray bar I want to know how much flow is to much on plants? I have blyxa japonica and cabomba furcata in the path of the spray bar on the other side of tank everything is almost falling over because of the high flow. I really don't want to have any surface movement at all to keep the co2 in. I tryed the other Power Jet Nozzle but it has to much flow, I also moved the spray bar kinda pointing at the surface but then it will get fast swirls. Any1 got any advise?
