You got it more or less pluming for the filter is under the tank and the Jebao return pump is for flow and it runs pluming in the rim of the top of the tank. The filter pad on the side there is to hide pluming and I plan on growing moss there as well.Set up is looking great, thanks for sharing the steps to the set up!
More details on the filter set up please. It looks like you are using a piece of Matala filter media as a HMF with the FX4 intake behind it? Also appears you made a spray bar?
