hooray!!! got a great deal on 2 glass tanks (10$ each!!!
) the smaller one, a 10g, is pretty nice, looks almost new but a few small scratches. but the 20g, while it is usable, doesnt have all that great of clarity... i was wondering, do any of you seasoned aquarists have some useful secret to clearing up the clarity on a tank? any recommendations for a good product to help with my problem, but wont cost me a bunch of money? thanks for any input you have!
