I don't have an updated pic cos I'm at work and I've recently upgraded my filtration. I have a 4' sump with around 30-40kg of ceramic media, lots of crushed coral, 2 denitrators and an overflow/underflow system. The overflow contains 3kg of Bacteria House in a "Bakki Shower" type system. The water then passes through 2 layers of fine foam (around 1" each) and 6 layers of thick (2"+) black bio foam. It then goes through the ceramic media and lastly into the return compartment (which also contains the denitrators, heater and pH monitor).
I'll try get a pic up later in the week, but not today as I'll be home very late..
Any questions just ask..
