BUMP! This is a great thread. I'm thinking about tiling my tank too with dark black tile. I have a barebottom tank right now and some of the pics above really make me want to switch to tile.
Can anyone who has done a standard 125g. 6 foot tank tell me exactly how many and what size tiles u used? im gona do mine soon. im so sick of the muck of sand and gravel in my tank. these tanks ive been seeing look amazing. Sand is hard to scoop lungfish poop from
Just remember that alot of fine crap will get stuck under your tiles. I had detritus build-up under them, and quiet a bit of black slime type algae would grow on the tiles. Still needs to be maintained.
