The other interesting option with these powerheads is the needle wheel that is included to regulate the injection of air into the water stream coming from the pump.

The water at the bottom of the filter is fresh and high in dissolved oxygen, so aerobic bacteria cultivate in the bottom half of the sand bed, and remove ammonia and nitrite, using up oxygen in the process. In taller fluidized-bed filters, enough aerobic bacteria cultivate in the bottom half so that as water flows past them, they remove most of the oxygen from the water, so facultative anaerobic bacteria cultivate in the top half of the sand bed where they remove nitrates. Not all fluidized-bed filters are tall enough to promote anaerobic denitrifying ba

One note on their use though. If you decide to purchase one of these, be sure to account for any reductions in flow rate or down time due to powerhead cycling in your calculations for total circulation needs.

This is not recommended because of the extra stress involved in netting, transporting, and re-acclimating the fish to the new environment.
However, if you dont have a choice, and need to bring your fish inside for the winter, be sure to have an aquarium air pump or small fountain to provide oxygenation. The fish should be fed infrequently, if at all, depending on the water temperature. pH, ammonia and nitrite, which sh
