berlin system

How good is the Berlin system?

 

pretty good just make sure you have plenty of live rock in the tank. I use the berlin method myself

 

I think most people are using at least some berlin for there filtering. I like to be redundant just to be sure so I now run berlin, wet dry and refugium but I started out on a berlin system and never lost any fish or coral. Like fisherman said be sure you have plenty of live rock and at least a three inch sand bed put in around the rock to make it easier to keep clean is also good. I found having about 1.5 or a little more pounds of rock per gallon worked well for me and about the same for the sand. If you are going light on the fish and just doing more coral you can have even more rock because you dont have to worry about swimming room as much.
