adding iodine to kalkwasser reservoir

[astroboy]

I'm thinking about adding Lugol's solution to my 10 gallon kalkwasser reservoir, which is hooked up to an automatic top off system, to get more even levels of iodine in my tank.

 

Does anyone know if this is OK? I wondering if there's some exotic chemical reaction between iodine and kalkwasser compounds that I've never heard of.....

why do you want iodine in your tank... and are you looking for ioDINE or ioDIDE? they sound the same and both are dosed in reefs but I see the latter more often

On the Lugol's bottle it says the ingredients are potassium iodide and iodine. I've read more than once that inverts, especially shrimp, require iodine to molt (or possibly iodide, I'm not sure offhand).

 

I've been dosing my 75 gallon with three drops of Lugol's per week for the past year and my shrimp molt every 3-6 weeks, happy as clams from what I can tell. In the entire year prior to that when I wasn't dosing with Lugol's I think they molted once or twice. In any case, adding Lugol's seems to be doing no harm to anything....

Just be cautious most people don't does what they can't test for. Iodine/Iodide being something that falls in that category. Also you may be getting your inform from a reliable source reefers with good exp... or forums filled with conjecture, vendor websites with a product to sell you, or on a label that wants you to buy a refill. IMO if you're doing regular water changes with a good quality salt instant ocean and the like, you have all the iodide and iodine you need.

I used to dose Lugols solution back in the day for Fiji Yellow leathers to brighten their color.

Salifert makes an iodine/iodide test kit, on which I wasted my money thinking I needed it, then used it only once. I had it on trade board a while back and got no responses.
