Aquarium Top Off Bracket

This is an automatic top off bracket for rimmed aquariums. The bracket will fit over aquarium rims up to 15mm in width. Simply put an upside down water bottle in the bracket with some airline tubes coming out of the lid for your own DIY automatic top off!

Be careful not to put too much weight on the bracket so that your rim does not break.

I wanted to design an easy to use bracket for rimmed aquariums since most printable ATOs are for rimless tanks or go on the corner of a rim making the hood impossible to use.
