Fish Tank Liquid Sand Filter Hose Holder

thingiverse

A crude attempt at a fish tank liquid sand filter is made using an inexpensive ~100mm O.D. zip-tie container and a 190GPH pump with a 12.7mm water line, along with a set of hose barbs - one 90-degree with a barb and threads, the other a direct coupler with a barb and threads. The goal is to keep the 12.7mm line relatively centered, preventing sand eruptions that empty out the filter. Note that this design has no support or gap at the bottom to save on filler filament and support material. Support is instead provided by ~20mm rocks at the bottom. This is a draft and alpha 0.2 version of the filter. An update has been made to add a top design, preventing aquatic life from entering the LSF and helping regulate flow a little bit.
