Using Gargeer Calcium Powder is a breeze. For insects, just put them in a bag with a bit of the powder and shake gently so the powder sticks to them. For salads, sprinkle the powder evenly on top. If your setup has UVB lighting, use the D3 - free formula. Without UVB, switch to the D3 - enriched one. As for frequency, it can be used regularly, but always watch your pet's behavior. There's no need to worry about over - supplementing, as it's designed to be safe. Store the powder in a cool, dry place to keep it fresh.
