Description
Component 3in1 is a comprehensive product of macro and micro elements, dedicated to marine aquariums, created based on the Balling method. The formula comprises highly concentrated calcium, magnesium, and KH in proportions that precisely align with the requirements of corals. Component 3 in 1 contains organic calcium salts, so it also works as a carbon source in marine aquariums.
Key ingredients necessary for maintaining the health and well-being of corals can be found in perfectly balanced proportions of magnesium, calcium and KH.
Component 3 in 1 provides essential macronutrients in a form that is easily assimilated by marine organisms. Additionally, it contains essential trace elements that play a key role in metabolic processes, coral growth, and maintaining intense coloration.
Thanks to its 3-in-1 formula, dispensing the product is very quick and easy. In addition, it eliminates the possibility of selecting the wrong proportions.
1 liter of the product contains 40000 mg (Ca), 1900 mg (Mg), 5800° (KH), and trace elements.

Aquaforest Component 3in1 for simplified Balling dosing
The Balling method keeps a lot of reefers up at night juggling three separate solutions, and Component 3in1 is the answer for keepers who want the chemistry without the choreography. It combines calcium, magnesium and carbonate hardness in coral-matched proportions in a single product, and because it uses organic calcium salts, it also doubles as a gentle carbon source. For busy Singapore hobbyists, that means fewer bottles to mix and one less thing to forget on a hectic week.
We usually recommend 3in1 for mid-stocked tanks with steady, balanced consumption, where the fixed ratio between Ca, KH and Mg actually fits the demand. Heavily SPS-dominant systems that pull elements unevenly often outgrow a single-bottle blend and move to separate dosing, but for many home reefs this is the sweet spot. Test on a fixed schedule and adjust the daily dose to your measured uptake.
