Been having trouble with a lot of surface scum from organics and Co2 build out of my inline atomizer. This cleared it up right away. Took a bit of time to get it dialed in using the pipe flow and my inline flow valves. My canister was taking in a lot of air as I had it 100% skimming the top. But wow, zero scum after a few minutes, traps any floating plants or food, and added a nice balanced surface agitation. Definitely recommend for any setup.
