The single pump should be fine. I prefer to have a bit of redundancy in my tanks but my tanks are also much larger so I have the room and with the flow rates I run a single pump becomes far less practical. I'll be sending you a pm shortly. I would defiantly change your plumbing such that both drain lines drop separately to the sump that way should there ever be a problem with one tube being restricted chances are that the other will be enafected and be able to take most of the flow. The vinyl lines should be fine for years to come on my 175g that I've had for about 5?years now has used them from day one I just can't remember if when we got it off a friend we put new lines on to it or not if not there close to 10 years old by now.
