A chemical function is essential for a clean tank because the water used for aquariums can have hard metals and other noxious chemicals that will affect the fish’s well-being. Cleaning up all the impurities from the water will ensure that healthy environment your fish need.
Last, but not least, the mechanical function of a filter is designed to remove the debris resulted from the fish’s activity. The filter will aerate the water inside the tank and help to remove the debris, creating healthy conditions for your fish to thrive.
About water flow rate
If you read the specs on various models on the market, you will notice something called water flow rate. This value is measured in gallons per hour the unit can pump.
