ok so i really dont need a tube of carbo just two tubes one with media and one with bio balls. my lights i was looking at retro fit lights that i can recess into the topon the side. here in another idea i had for the filter is to put a 3/4 pipe in the top of the two inch and drilling holes in it so it can drip down into the media and bio balls
