Review on Thunder Parts ECD270 Bubble Diffuser by Leanne Steltz

For the price it doesn't seem to get any better. Mine was only plugged in during the day, just over 1cfm at 7-8ft of water, but it bubbles very well. I connected the shaft to a 3/4-1/2" zinc plated cone adapter and then threaded a 1/2x2-1/2 zinc plated steel pipe nipple to 1/2fnpt x 1 which I threaded through a hole in the brick for added weight. /2 barb barb 90* fitting to connect to my 1/2 weighted hose.It looks like it comes with a check valve to keep water out if the pressure drops but I can't confirm.This is my first hose of this type diffuser, so there is nothing to compare.
