Component 3+ 5L

Component 3+ is a liquid supplement for reef aquarium keepers who dose magnesium regularly and want trace elements added in the same routine. It is sold in a 5 L container and is intended for marine tanks where stable magnesium levels are needed to support corals.

Why it matters

• The formula contains magnesium (Mg), mineral salts, potassium (K) and boron (B), so one product covers several elements instead of separate additives.
• Each 25 ml dose raises Mg by 0.38 ppm per 100 L, which gives a measurable reference for calculating dosing in a given tank volume.
• It is part of the Component 1+2+3+ system, based on H. Balling's method and modified with trace elements, which is meant to be dosed in equal amounts on a regular schedule.
• The system is aimed at keeping calcium and magnesium in the ranges the manufacturer gives for reef tanks (Ca 380-460 ppm, Mg 1180-1460 ppm), which supports the correct balance of other trace elements.

What it works with

The product is intended for marine reef aquariums and fits into a regular dosing routine with the other Component products. Dosing rates should be scaled to the water volume of the tank, using the 0.38 ppm per 100 L Mg figure as the basis. Component 3 contains Reef Mineral Salt, which the manufacturer describes as needed for stabilising parameters in the aquarium.
