Brightwell Iodion 250 ml

Brightwell Iodion 250ml is a concentrated iodide supplement for marine aquariums. Iodine can be depleted through biological use and removal of organic material, including skimming and adsorptive filtration, so supplementation should respond to measured requirements.

Shake before use and follow the bottle's dosing instructions while monitoring iodine. Consider other trace-element mixtures and water changes when planning additions, since they may already supply iodine. Iodion is a maintenance supplement; closed corals or poor colour alone do not establish that an aquarium needs more iodide.
