True, will work fine.
After some experimentation, I now have my UV set up as a HOB/UV. Small pond pump, tubing, and some CPVC let me move the thing from tank to tank.
I do not run it 24/7 on any single tank, but move it around on a rotating schedule..
48hrs per tank, per month is working for me.
Butt ugly on the living room tank, but for the, fish floating in air look, this unit gives, it is worth it
