A 20-gallon tank needs a filter rated for a minimum of 100 gallons per hour (GPH).Heating: As a basic general rule, fish tanks need 3 to 5 watts of heating unit power per gallon of water. A larger tank requires either a higher-wattage heater or several heaters put at opposite ends for even heat circulation.Lighting: If you plan to keep live marine plants, tank height matters.
