Cobaltum Lab 200ml

This 200 ml bottle of cobalt concentrate is aimed at reef keepers who already test their saltwater and see low cobalt readings. Cobalt is a trace element that the aquarium cannot replenish on its own, so this product lets you correct it in small, measured steps instead of guessing.

Why it matters

• Each 1 ml raises cobalt by 0.0005 mg/l (ppm) in 100 litres of water, so dosing is easy to calculate for your tank volume.
• Cobalt is a component of vitamin B12 and plays a role in metabolic processes in the aquarium's inhabitants.
• The manufacturer links cobalt to fish colouration and to the growth of certain beneficial algae and bacteria.
• The recommended target range is 0.0001–0.0006 mg/l (ppm), giving a clear reference for when you are within limits.

What it works with

The product belongs to the reef salt and micronutrient supplement range, so it is intended for saltwater reef aquariums. The manufacturer advises dosing according to ICP-OES test results rather than on a fixed schedule. It is designed to be used alongside other Aquaforest Lab trace elements when your tests show several parameters out of range.
