Okay thanks for the answers. No i didn't know not to use aquarium salt, thanks for asking me. I am planning on having live coral in the tank too. I am so exited, I've never had a saltwater tank before, only freshwater. One more question, when do I add more salt to the tank water? and do I add as much salt as I did in the first place?
Read, Read and Read some more...you need to really educate yourself on this side of the hobby, mistakes can turn out to be expensive. Check out the journals of your predecessors in the saltwater section and learn from them, adopt a Guru on this forum, someone you know you can trust and has been there and done that. Doing things this way means you can keep setbacks to a minimum. Do the research first. Good luck with your venture into marines.
