I was just thinking earlier about the ridiculous number of supplements and additives which are a huge part of the hobby nowadays. Not only are a lot of them essentially snake oil, many are ridiculously expensive as well! I'm not saying that there's no place for some supplements as some actually are essential such as calcium, magnesium, and alk along with a few others in the hobby but it seems to have gotten way out of hand. It seems that it would be much better to maintain a tank in as natural a manner as possible. Why not get back to the basics of establishing a new tank with some quality live rock and instead of soaking your fish food in vitamin supplements feeding them a much more natural diet which would supply them with the vitamins and minerals they need naturally? With the exception of bacterial additives (and some of them are unnecessary as well) it almost seems like we're trying to support creatures from some other planet sometimes. I simply feel that the most natural way is the best choice often for both the animals and your wallet.
