SPS question

[Oceanic]

I dose 4 drops weekly to 160 gallons, I find this gives me the best results and I also do not test for iodine.

Lugols directions does say to dose 1 drop per 25G per week. This would be 6 drops for me; however, I have just stuck to 4. I also dose 8 drops of Kent Fe (iron) monday and friday.

Oceanic - whats your water volume to Lugol drops ratio?
