Once in a while however, you may come across a situation where Berlin plus DSB may just not be good enough for the application. A typical case would be that of a predator tank. All meat eaters generate lots of waste, and NH3, NO2- and NO3-. It may be and usually is too much for these filters to handle.

What we normally do in this case is to use trickle filters coupled with denitrifiers, or skip the denitrifier and do more regular water changes of larger amounts.

You can still have the LR and protein skimmer and DSB, and this will help to a certain extent, but not on their own.
