I have been doing some research on sumps as of lately. I am thinking about incorporating one into my SW
aquarium I am building. I have some questions, though, that I wanted to run by everyone... This will be a 29 gallon reef tank with 2-3 small fish max. Everything else will be inverts. Tank will be using the Berlin method of filtration.
Do I need any filtration in the sump other than the protein skimmer? If I understand the Berlin method properly, I don't need anything in the sump other than the protein skimmer, heater, and pump. This correct? Why do I see people that have filters in their sump? Are they using another method of filtration other than the Berlin and need mechanical filtration of some kind?
The reason for using a sump really caught my eye when I saw I could hide everything under the tank out of view. I could also hook up a kalkwasser drip line under the tank that would drip continuously into the sump. What a great idea!!
Went to Wal-mart and they have 10 gallon tanks for sale at $8.99. What a cheap sump that would make...
