Practical tips for use in the discus aquarium

For discus, a filter with a flow rate of 4-6x the tank volume per hour is recommended. Example: for a 200L tank, choose a filter rated at 800-1200 l/h. Discus prefer moderate current without strong turbulence — direct the filter outlet toward the tank wall if the flow seems too aggressive.
