Pic of how it looks on my tank of marbled crayfish. Its a bit green in there, I put a bunch of green water with daphnia magnas for the crays to eat (they will get to them when the lights go off right now they are out of reach).
I dont think this is going to work real well because of out gassing =/ The tubes slowly fill with bubbles that get bigger and bigger until they start joining together that can stop the flow.
Anyone use a small glass drill and poly tubing to make drilled tanks on the cheap?
For example: about 2/3 down on the height of the tank drill a 6mm hole 1/2 inch from the side. Form some 1/4" poly tubing into an "L" shape and press through hole. VOILA done?
