As long as you have a syphon break so it does not back syphon. I run my RO line to display, use a Maxi-Jet bracket with the airline clips they provide cliped to the glass crossbrace. I have 2 lines in bracket, RO above 1/2" above water and gravity feed for my Calcium reactor about 1 1/2" below waterline. If your holding tank is above where it goes it will still flow after pump cuts off.
