Are you saying just add to the tank or are you saying to soak the food in it? Dietary suuplement
Sorry, should have clarified...I used it as a dietary suppliment by adding a drop to my food (along with selcon, garlic and vita-chem) and letting it soak. I can not emphisize enough that you should stckly monitor the iodine levels in your tank if you do this. it helped my regals HLLE
tremendously. However, stray voltage could have also been the cause. I replaced two of my poerheads at the same time that were making funny noises.
