Yes, get a LARGE discharge pipe!!

It helps to save precious time. secondly, it can clear debris easily. i hate to use my hose to chase those mini debris during water change.

there was a discussion during the RG Live. One of us injured the fish during siphoning , the fish swim towards the hose and got stucked by the siphoning effect, due to the pressure, its almost certain the fish will get physically damaged if you didn't notice until its too late.

we discussed the work-around, one of which is to slice the outlet into a irregular shape, which would prevent the fish from getting sucked into it, the other is to drill a small hole away from the outlet, which will lessen the presssure and allow the fish to swim away.
