AquaClear 50 Filter Spacer

This is a spacer grid that you can place at the top of your AquaClear 50 Fish Tank Filter to push down the BioMox ceramic rings into the water.

I printed in PETG with no supports. You may need to pull up the filter basket to push this in at the top (see photo).

I was having an issue where half of my ceramic rings were sticking up out of the water.
