Technical Background
Brightwell Aquatics Lugol’s is an extremely powerful iodine solution. It should only be used by advanced reef aquarists to dose iodine as well as to create a dip for corals and their allies.
The importance of iodine in a reef aquarium cannot be overstated. Presence of iodine is vital to hermatypic invertebrates (i.e., corals, clams, and their allies that harbor zooxanthellae) because it is used to detoxify excess oxygen produced by zooxanthellae. This oxygen irritates sensitive tissue. Corals and clams that appear to shrivel or close under intense lighting are attempting to shade themselves from the excess oxygen.

Joshua Taylor –
Used Lugol’s for the first time on my live corals after a lighting change. The corals responded well, opening up and showing more color. It’s a bit tricky to dose correctly, but once I got the timing right, it made a noticeable difference in coral health.
Maria Dowd –
This product is powerful and effective for iodine dosing. I use it sparingly to maintain iodine levels in my reef tank. The dip method works well for cleaning and conditioning corals.
Anthony MacDonald –
As an advanced aquarist, I found this product essential for managing oxygen buildup in my reef system. The corals have become more active and less stressed since using it regularly.
