venzi Posted August 10, 2022 Share Posted August 10, 2022 (edited) Hi. What would be the recommended way to test for overall water flow? I've seen videos where something that looks like food coloring is used to see how it disperses and spreads in the tank, but don't know what product was actually used. Is there a guide/video explaining how to test for proper flow? Edited August 10, 2022 by venzi Link to comment Share on other sites More sharing options...
