Ok, been thinking about some stuff and wanted to get some info on it before I jumped in. First, should I be concerned much with my Iodine/Iodide levels with just live rock/fish/snails/hermit crabs? And if so, what is a good product to raise the levels. Another thing, is getting a UV sterilizer a good thing or not? I've heard pro's and con's about them and was wondering how many Reefers have them. Also, I have a maxijet 1200 powerhead that I turn on just when I add chemicals/invert food. When its running the fish act like the current is too much and stay low in the rockwork. Is this too much for my 75gal or should I not be concerned with how the fish act and run it constantly. Also, should I point the stream up or down towards the rockwork. Thanks again for all the info you guys can give me!
