RatPack, do you think it is more the calcium than the iodine that helps the xenia?
When I bought this from the LFS they told me to add calcium for it to flourish, nothing about iodine. I have heard of people crashing their tanks with iodine use.
I currently don't add anything to my tank, what about phytoplankton woud it do anything for xenia?
For a 10 gal how much calcium would you add?
What about phyto?
