I have a 75 gallon reef tank and I have been adding iodine but not the Lugol's Iodine until just recently. I never have tested my water to see what the Iodine level is, however, I tested it today and it shows no iodine in the tank.

My question is, can someone tell me how much of the Lugol's Iodine do I need to add to my aquarium to bring the iodine level up to 0.06 that is recommended for saltwater? I don't want to add to much, but the directions for use are for weekly additions, assuming your iodine level is where it should be.

Thanks for any help you can give. I need to bring up recommended level up asap.

Thanks!!! :confused:
