But people are still looking cause i was, and I did mine yesterday. FX 6 wasn't made for a shallow tank, and it's probably overkill. I use it for an aquatic turtle which are very messy. don't cut it from where anything connects just the other side. But no matter what your gonna have to cut...
Your going to have to cut parts of both tubes, one connects to the hose (the one with no lines, and the other tube connects to the strainer (one with lines). It will be loose and easy to take apart after cutting. But because it's an intake it won't come apart.
