A lot of people say they hate tetra but the big problem is education and experience. I know in my younger years before I read a few "goldfish for dummies" type books I over cleaned everything. Thank for the extra info.
I had problems with one I bought recently too. i don't know if they're making them differently now or what. I sent mine back and the replacement is quieter (still not as quiet as the older ones though)
My tank uses a 75gal hob. Water goes up past the sponge part first, then through those white biomedia macaroni stuff. looks like yours goes through the sponges second.
i use tap to clean all my filters .never had any issues.i think i'm killing a little bit of the bacteria in the system.seeing that it is in everywhere in the tank.
