This takes place several times per day, usually 3-9. The downfall is that you must use denitrification liquid to keep the units functioning, and they do take a lot of extra space due to their large sizes. However, they do a wonderful job in removing all excessive nitrates. The bacteria fuse to the media feeding spheres where they multiply and process the water as it passes slowly through the unit. These are an innovative approach to denitrification.
Water trickles into the top via gravity and falls through the other end, back into the sump.
The coil is very dark and narrow, and as the water passes it will lose most of its oxygen content, offering a perfect environment for the anaerobic bacteria necessary for denitrification. Choosing a denitrifier for your tank can be a bit tricky, given the different styles available. To help with your decision, please don't hesitate to call. The N-Forcer operates to reduce nitrates in the saltwater aquaria in a slightly different manner than anaerobic bacteria. It is an electrochemical device consisting of a flow cell containing electrodes and an electronics control circuit.
