Grizzly Posted May 7, 2021 Share Posted May 7, 2021 (edited) I was curious if anyone knows the diameter of the rubber adapter for the output for the fluval 306? I want to attempt to make a spray bar but am unsure on the size of pvc to buy and don’t want to take my output apart just to get a measurement. I tried looking online but am having difficulty finding it. Edited May 7, 2021 by Grizzly Link to comment Share on other sites More sharing options...
