Re: dosing iodine
I am also working with SPS for the first time. A couple of my pieces looked to be turning brownish...and right away too...yet at the same time they appeared healthy. For what it's worth, I was told that brown colored zoanthelle flourish quickly in moderate lighting and that the colorful stuff only flourishes in the brightest of light. So I gradually moved those 2 pieces higher in the tank and they're just starting to color up again but only in a couple small spots. Also, I was told that it's not uncommon for SPS to change their color...apparently they will take in the color of zoanthelle that suits their needs and is readily available in the tank. I've personally found that anemones will do the same thing. I've had BTA's and rock anemones obviously exchange zoanthelle...never entirely, but significantly just the same. Place a red BTA beside a bright yellow fluorescent rock anemone and watch what happens.
Also, I was told to not directly feed SPS....that they'd prefer cleaner water over the food and that they can get everything they need from proper lighting and from what comes their way when other tank inhabitants are fed. So far that's been working out but I haven't kept SPS long enough to know if it will work long term. Just an FYI I guess.
I had never intended on keeping SPS in this particular tank but I had some clown gobies living in a large brain coral who got booted out by 2 goofy skunk clown who decided they wanted to host it. The clown gobies looked so sad. :o( They live in the branches of SPS in the wild...so I thought I'd give it a try. This tank's water chemistry is not ideal for SPS and never will be...so if it fails, it fails. Then the gobies will just have to live in SPS skeletons. I bought my SPS from Live Aquaria and they suggested some pieces that might be more forgiving.
