All Aquaforest formulas are adopted to dispense 1 drop at 100L of water. However, it should be remembered that each aquarium is different, depending on coral quantity. By introducing new products to aquarium you should begin dispensing 1/2 (even 1/4) dose and observe how the corals respond. Then gradually increase the dosage to reach the target. Corals should be fed at night when they extend their polyps.
