whats a cheap black background for my tank

[scottswald]

i painted mine with a brush while it was up and running, it was hard to get behind it though because it was close to the wall

The reason I used tint was because I was tired of water getting inbetween the tank and the usual background when my O's decided to slosh around.....

I've used black trash bags, black poster board, and black or dark fabric from a fabric store. A trip to Hobby Lobby, or a fabric or hardware store should provide you with plenty of economical options.

Just paint it black

Try the limo tint. An LFS here did it on all their tanks and it looked super clean.
