Hi, please how do I set the output from two external filters to make the aquarium water flow optimal? I have two Eheim Classic 600 external filters for my 360 liter aquarium. I have a problem with green algae. I have lighting for Eheim PowerLed Daylight 3 x 34W - 4080lum. So far I have switched off one ramp, adding CO2 from the bottle. Thank you for your help.
