Water carrying these pollutants must come in contact with the bacteria colonies on the rock and be broken down. The porous surface of live rock is home to millions of bacteria responsible for breaking down ammonia, nitrite, and nitrate. Using circulation pumps and wave makers in a reef aquariumĪ reef aquarium containing live rock, corals, and other invertebrates requires specialized water movement. This allows you to direct water flow in two directions while only mounting a single pump on the glass. The SunSun JVP-202 Dual Wavemaker Pump has twin water pumps with rotatable nozzles. If you have a large aquarium you may need two smaller pumps instead of a single large water pump. Adjust the position of the water pump so it forces water into that area. Take a look where debris tends to accumulate in the tank. If you have positioned the outflow of a canister filter on one side of the tank, aim the circulation pump toward the other side. Like a freshwater aquarium, all you want to do is keep the corners and back side of the aquarium flushed and clean. Fish-only aquariums decorated with synthetic resin corals and other items that block water flow and allow debris to pile up behind them.Īdding a powerhead or circulation pump will keep debris suspended so it can be captured by the aquarium filter. Water movement in a fish-only marine aquariumĪ saltwater aquarium containing only fish will benefit from improved water flow within the tank. The suction cup mounting system makes it easy to position the pump anywhere in the tank. The Hydor Centrifugal All Purpose Pump comes in several flow rates and is designed to create gentle water flow throughout the aquarium. Consider positioning the water pumps a little lower in the aquarium to avoid loss of CO 2. This will drive off carbon dioxide and reduce plant growth. Position a basic power head so your plants are gently washed in the current but not bent over due to extreme water movement.Īvoid causing a lot of turbulence at the water surface. Plant growth will become stunted and algae can take over the plants.Īquatic plants don’t need strong water flow or waves moving back and forth. This means your plants are not efficiently adsorbing carbon dioxide and nutrients or releasing oxygen into the water. When there is insufficient water movement across the leaf surface, a stagnant layer forms. Aquatic plants absorb carbon dioxide and nutrients through leaves and stems. A freshwater planted aquarium has a different water flow requirement.Īquatic plants thrive when they are surrounded by a gentle water flow.
