An airstone, whose purpose is to gradually diffuse air into the tank and provide oxygen for fish to breathe, is an necessity to have around your house if your are a lover of aquatic animals.Pawfly air stones are made of high quality non-toxic mineral material. With high temperature sintering, the stones are sturdy and durable, have high dissolved oxygen rate and create even and tiny bubbles rather than a limited number of large ones.
