You can save you investment on the Phos reactor,skimmer,wool and Denitrator.
You can further save on the energy use by the above equipments by using LED algae scrubber

3.I'm using various power supplies from 30V to 24VDC, ranging from 5A to 3A.

4.No fan in used.

5.Aluminium sheet can be found in most aluminium hardware stores, mine cost about $70.
