Sump

My sump size is about 28"x20"x20" with 4 compartments.

Leftmost compartments are the water incoming from the main tank. It is filtered by the filter wool. Then it is passed through the refugium. This is where cheato algae is located and the algae acts as nutrients exporter to reduce the nitrates, phosphates, etc. The cheato algae is powered by a compact fluorescent for photosyntesis process. 

The next or the middle compartment is where I house the beckette skimmer and the calcium reactor.

The last compartment contain the 2 set of fluidised reactors, skimmer pump and the outlet to my eheim pump 1262 which is located outsump.
