I bought this setup because I got a great deal at Petsmart, $179 for tank, stand, led lights, glass hood. I had a coupon and some rewards to use, it was on sale for $269. Right now I'm using 2 Penguin bio-wheel 200 filters that I had spare. Seem to be working great and keeps the water clear. I was just wondering what filter do others use on their corner aquariums? I've been thinking of changing.
