After my african cichlids had successfully destroyed my 2ND! AQ 70, I decided to replace it with a cannnister. I had two AQ 70s going on my 50gal, one of them is out of commission now, and the other one is still going. I just picked up an XP3, and some polyster fiberfil. I know you're not supposed to get hypoallergenic, the stuff I got says non-allergenic. I just want to make sure that this is safe to put in the filter.
Another question, should I keep the AQ 70 going along with the XP3? There's no such thing as too much filtration, I just didn't know if it would be worth it, as I'm already gonna be way overfiltering my tank.
EDIT: Also, is it ok for the spray bar to be placed where air bubbles are going to hit it? Since it's the output, I figure it would be, but I just want to make sure it won't affect the cannister at all. The intake will be placed away from that though, so that's not an issue.
