I am planning on upgrading the fish in my bedroom, and I am wondering what my filter choices would be. Normally I use sponge filters, but the air pump humming would keep me awake. I was using an aquaclear, but they do make a crackling sound that already drives me crazy. I was thinking canister, but the cost is prohibitive.
Also, I hope on having a sand substrate. Any ideas?
