As I said before, I have done the same routine for 2-3 years now. I only add iodine once every 3-4 and possibly five times I do water changes. And I only add maybe 4-5 drops...this is a 135 gallons total tank. I wouldnt think this would have any adverse effects on it. Also I would think I would have had more of a problem before now.
Im not arguing but just restating my point. I have heard they dont make iodine test kits..maybe I will check into this. Also 3 out of 3 LFS
said it was that the CBS probably was just old. I have had him at least 2 years...dont know if this is true but just relaying the info on. Also tested my water at a LFS
and all is well as I stated above. All shrimp in my tank tonight are ok...we shall see.
