This aquarium was actually started July 2007. I have done many modifications to this BioCube in the goal of growing an SPS aquarium in a small tank. I started by building a 3 sided raised platform on the bottom of the tank. about 2in. high topped by black egg crate. I originally put sand all around that but it was always blew away from the front staying only on the sides so I reduced the amount of sand and used a larger size (1mm to 2mm grain size). The following set of pictures I will show the modifications that worked.

I modified the sump compartment to allow me to put in a lot of stuff... larger felt filter. large protein skimmer, heater, refugium for chaeto and live rock, external pump and chiller, auto top-off, PH probe, um what else oh yeah, calcium reactor.

I highly modified the sump area using a dremel tool. Most all of the parts I needed I made from the parts that I removed.

Filtersock insert and sock. I made the insert out of parts that I removed from the back of the BC29 and a  2 inch bulkhead.
