Reeflowers Minerals gH+ Fish Aquarium Water Conditioner, 2.9-fl oz bottle

In reef systems with an average bio-load a weekly dose of 1/2 tsp (2 mL) per 26 US gallons (100 liters) is recommended. If used together with ReeFlowers Enriched Kalkwasser add 1/4 tsp (1 mL) of ReeFlowers Minor & Trace Elements per 1/4 gallon (1 liter) of Kalkwasser solution. Do not exceed 1 tsp (5 mL) per 1/4 gallon (1 liter) of ReeFlowers Enriched Kalkwasser solution weekly. Once the desired calcium level and alkalinity are reached, periodic testing will determine system specific consumption rates and allow a dosing regimen to be established. Do not overdose as this may be harmful to the organisms in the tank.

For reference 1 cap = ~1.2 tsp (6 mL)
