Turning off one stack without plugging it off will just cause water to flow
down one tube and up the other with no or very minimal flow. Better would be
to reduce the flowrate on both tubes at once, and watch the ammonia/nitrite
levels for a week or so. If no excess builds up, reduce it further.
Eventually you should be able to get the UGF turned off provided the Fluval
and plants are providing enough biological reduction.
