I gave the filtration a overhaul. The canisters are gone and I have completed my insulated sump. I am now running 3 overflows that feed the bucket filters which are sealed into the esky lid. These are filled with a mix of Aqua clay, ceramic rings and Seachem Matrix. Not shown is the layers of filter floss for mechanical filtration and the drip trays. The water is returned to the tank via 2 x 4500 lph pumps. I now have my heaters in the sump/filter as well.
