1+ on all that was said. One other thing you need to think about(and I made this mistake) is a 25 is kind of small if you are just starting out. People go smaller, but they REALLY know what they are doing and if you, like me, are new, you are going to crash your tank if you don't do it right the first time. Please do yourself a favor and be patient. I wasn't and haven't (knock on wood) crashed my tank yet, but I did get an established tank. If you have always wanted to get a salt set-up like I always did, you are going to be throwing a lot of money, like I did, down the drain. You probably will, once all is said and done, be spending over a grand on all this stuff to do it right. This all does, though, depend on what you want to do. Fish only, Fish with live rock, or full reef. I agree with Bob, read up first, go to a nice local fish store, and enjoy what they have and then decide what you want to do. I only say this to give you a head's up on what is coming. I do have to say, all warnings aside, it really is worth it. It is STUNNING to see what can grow in a fish tank!
