How much Lugol's Plus to add to a 125 gallon?

[arnjer]

I lost my instructions and the bottles doesn't say.
Do you even still add it? It seems like I used to add 5 drops to a 90 gallon.

Thanx,

Jerry

I agree. In general, you should only add this stuff (or any additive) if you can accurately test for it before and after. With iodine the potential for overdose is significant. It is far safer to introduce iodine through partial water changes. Iodine test kits are hard to use. I have a PhD in chemistry and I find it almost impossible to get an accurate reading.
