@funkman Way to go! Thats what I talking about.
I have a 38G that has been running continuously since 2004. I have always used Marineland BioWheel Filters on this tank. Prior to having plants (added Feb 2011) The BioWheels always had a thick layer of bacteria growing on them. After the plants became established, the biowheels became void of bacteria, and since have been removed.
I would like to ween the tank off the filters entirely and reduce them to simple power heads moving water around internally.
I recently read that a engineer knows his work is finished not because anything else can be added to the design, but that nothing else can be removed. Its simplicity that I seek.
