I hear that iodide is good for cheato, correct? Well I bought a bottle of Kent marine Iodide sub. On the directions it reads: Shake bottle well and add 5ml per 50gl every week or 8 drops per 50gl per day. What's a drop? They suggest daily dose. I know it would be 5ml divided by 7 that would be like .71ml per day, right? Anybody do daily dosage? And if so how much do you add? Thanks....:thumbsup:
