I just set up a 120 gallon tank in my living room to add to my existing 360 and 450 gallon tanks. They are all on a central drain system that runs out to my yard. The two older tanks have been running on a trickle for water changes for a few years now and I love it. I wanted to add the 120 to this system and also update my plumbing.
The old system is a copper pipe coming from my laundry room that is behind the fish tanks. The pipe Y's into two hose bibs and I ran a hose to each tank and adjusted the flow with the hose bib knob, very simple but hard to maintain a constant even flow.
