There is a sponge on the return pump in my sump, should I take it off? It is covered in nasty and chaeto. Also there is a metal clamp holding the hose to the pump, it is rusted, should I remove that as well and use a zip tie?

Thanks!!
 
if its aluminum or stainless steel it won't rust. as for the sponge, you should indeed take it out or you could have nitrate increase

It is rusted, so should I take it off? I can't imagine rust is a good thing for a tank?
 
Thanks leo for the help, removed both. The sponge was very disgusting, blah, yuck. I have filter floss on the intake that I change every few days, but left that sponge on there from when I got the tank. Hopefully some of the new media, removing the bio balls, and now that sponge will get the nitrates down even more.
