Our water crystals are used for feeder insects to get their daily water allotment! Without the mess, smell, bacteria, fungus and death due to falling in the water bowl! This will go a long way in making sure if you are away that your feeders will not go thirsty! A nice way to up the vitamins is when cooking any vegetable is to save some of the water and use it in the crystals a little at a time.  A few grains of crystals goes a long way, experiment with them starting small and working up to see how many you want to use at a time.
