Eco Sustainable Aquarium

Has been an aquarist since I was young.  Now coupled with fisheries degree.  I have my simple aquarium.  Like most fresh water aquarium owner, enjoy their pet fish swim gracefully in the tank.  But unlike most fish owner, I am lazy and no patience to change water so often, in fact I hardly change my fish tank, only top up when the water level is low.

Dirty water gravitate down and up by submerge pump

In order to do that, some effort needed to be put in.
