JUWEL Bioflow M Surface Skimmer

thingiverse

What is this? It is a surface skimmer that attaches to the outlet of a JUWEL Bioflow Filter M. What problem does it solve? It removes film on surface by mixing it with the water outlet of the filter. The working principle is the same as for the AQUARIO NEO Skimmer but tailor-made for the JUWEL Bioflow Filter M. Does it work? Yes I use it myself in my JUWEL Lido 120. It came with the JUWEL Bioflow Filter M. I designed the skimmer based on this filter. I don’t know if the outlet size is the same on the L and XL sizes but if it is then the skimmer should fit them too. The skimmer consists of three parts, the Inlet Floater, an Outlet Pipe and a Bernoulli Pipe. I have moved my filter to the left side of the tank and I am not sure it is on original hight. I therefor added three Bernoulli Pipes of different heights. The Normal one probably works but you can use the tall or short one depending on your surface level. I also added two different Outlet Pipes. The Normal one and one designed to be attached to [additional pipes](https://www.thingiverse.com/thing:6087117) I made for the JUWEL Bioflow Filter M. Mix and match based on your need (if unsure pick a set of "Normal").
