can't stand the screaming type of noise after a while, even if it can be quieter. I don't feel safe restoring everything and keep an old tank without knowing how the previous person treated it.
I think this size/type is great for home used, 20 gal. Even 15 gal is fine too. Too bad, looks like they don't make it anymore?
