What was that response for?
Dogstar has a valid point, not only for you, but for every hobbiest on this message board. Before doing anything to your tank, whether it be dumping in an additive, trying a new piece of equipment, or getting a new fish/invert/coral, it is always best to question FIRST before you act. It never hurts to post a simple question. With a resource such as this forum, it would be silly not to question things yourself.
