Frozen Food Aquarium Feeder

thingiverse

The Aqua-Thaw is a compact, easy-to-use defroster for your aquarium. Simply clip it to the rim of your tank and let it do its magic as it slowly thaws out frozen food blocks. This clever device keeps pesky ice chunks from getting sucked into overflows or filters, saving you time and hassle in the long run. Just be sure to keep the water level high enough that half of the Aqua-Thaw is submerged for best results.
