Yes, you can use sterile water to top off Darts when loading with BAM.
In fact, we (at Wildlife Pharmaceuticals) have found that you can effectively use any of the solutions listed below, as long as they accurately meet the descriptions.
1- Sterile water is water that has no microorganisms living within it. Sterile water, though sometimes distilled, is not the same thing as distilled water. As some microorganisms can survive at high temperatures, simply boiling water may not be enough to sterilize it.
2- Physiological saline is a 0.85% Sodium Chloride solution made in water.
3- Lactated Ringer's Solution is composed of sodium chloride, sodium lactate, potassium chloride, and calcium chloride. It is normally used for electrolyte and fluid replenishment and can help rehydrate animals and restore electrolyte balance.
