I went trough some aquarium supplies and put together my UAS for testing pusrposes.
It will run in-sump where the outflow from my waterfall is.
I came with an idea for testing: I've switched the air pump together with the lights, just to see if that impacts, later i'm planning to reverse it..
For the coming week it will have to do it with "left over" light only in my cabinet, but soon a CFL will be installed for it.
So updates Soon..
