Coral Essentials Coral Power Barium is a microelement that should only be strictly used in conjunction with a reputable ICP analysis company. We try to match every element found in natural seawater and as close to levels present in their natural environments. Only with consistent ICP analysis can you feel confident your corals are receiving absolutely every micro element that they would in the wild. 

Dosing requirements: Shake well before use. 1 drop / 100L of tank water only after ICP results have arrived.

For the advanced aquarist: 1ml (20 drops) will raise the Barium levels by 0.05 ppm (mg/L) for each 100L of tank water. If  you know the lithium depletion rate then dose accordingly.

Size: 50mL
