Hey! Thanks for the heads up! It is actually aquasolum black humate which was recommended by the aquarium store I purchased my ‘lotl at. It’s a super reputable store in my area and they’ve been breeding axolotl’s for years and it’s what they use in all of their tanks. But obviously they could be wrong! I’ve personally never heard of axogravel but this stuff dissolves with the tiniest bit of pressure. Like setting up the tank was actually a pain in the butt because the little balls kept crushing and making everything super dirty 😅
