Thanks for all of the replies. I do have one question though: Can I switch to a wet dry system easily? I don't have holes drilled, so I would imagine that I would have to wait until I purchase a new tank. Well, I guess that this is just more motivation to get a much larger tank to house my sharks. Thanks again!
Also, AC, the sharks are beautiful. I've been looking for an epaulette for many months in the denver area, but I could never find someone to order me one. In addition, I don't have any pics of the sharks, but hopefully I will soon.
Yours,
