What is a good product to add iodine to your system for sharks? i've came across a seachem brand but wasent sure where to go from there. Ady advice on testing and maintaning the correct level is much appreciated.
The benthic sharks that require iodine need it consumed (vitamin supplement to make up for the fact that they aren't getting live food), not as a trace element in the water. There are a few good shark/ray supplements out there. Mazuri makes one of the best.
