I want to buy a fluval 404 filter working or not. The only thing it needs to do is hold water and not leak. I am going to add this filter to a close loop. I need a few more GPH for these hard corals I got from the meeting. Also I need a easy way to add/change lots of carbon. I am willing to pay around $25 for a broke one. Hope someone has a 404 laying around. Thanks.
