Brightwell Aquatics Magnesion Liquid - 500ml

Brightwell Magnesion Liquid 500ml is an ionic magnesium supplement for marine fish and reef aquariums. Magnesium participates in reef skeletal material and helps maintain the relationship between dissolved calcium and carbonate, making it an important parameter to check when calcium and alkalinity are difficult to manage.

Use the liquid formulation's directions with a reliable magnesium measurement and the system's actual water volume. Adjust the maintenance amount to consumption instead of dosing automatically because corals are present. This bottle is Magnesion liquid; powder formulations have different preparation and dosing requirements.
