Wow first time I try dosing iodide and I'm impressed! My mushrooms are double in size and zoas look a tad bit bigger too. Hope this helps color up my space monsters. Thanks for the suggestions everyone!
Conservatively the test kits are $45 for just the iodine test. So screw that. The bottle says drop per gallon each day. I did less than that to be safe. My system is 40 g I only did 2 drops a day.
