The splendid colours of corals will only reach their full potential when all needed trace elements are available in the water.
The dosage of Colombo Marine All in One is linked to the calcium absorption, this way we achieve the controlled addition of trace elements such as potassium, iodine and iron.
Based on the calcium test you add Colombo Marine Calcium+.
Add 20 ml Colombo Marine All in One every 100 ml of Colombo Marine Calcium+ you are adding to your tank.
