I've been thinking about removing this from my tank for while because the noise generated from it is unavoiable. Even the expensive one still don't cut it. How can you guy get away with this?

My 83 gallons tank contains 9 discuses and plenty of tankmate such as 10 blackneons, 6 angel fishes, 7 zebra danios, 1 clown loach, etc..Plenty of plants. Sound alot but it still doesn't look too crowded actually.

Cheers.
