Here is what happened: I found a really good deal on a saltwater aquarium and went for it because my fiance really wanted one. The kicker is that I had to either commit to getting it or not immediately, and I really have NO saltwater experience. AT ALL. I know the internet is a beautiful place, but I really have no idea where to start, so please either give me a crash course or help point me in the right direction (crash course would be faster).
I know this is not a saltwater forum, but there must be SOMEONE here who can help me :D We are so excited at this opportunity to expand our aquarium experience and help us grow.
Here is what I know about the tank: The tank has been active for 3 1/2 years but I am not that confident that it has everything it should have. It is 55 gallons with live sand, very few live plants, some creepy crawly things, one fish, one or two small live rocks, and a heater. There are three HOB filters for it but they are all just walmart filters, however one has nitrite rock. There are two different kinds of lights (can't really remember much about them). Came with a lot of stuff buuuuuuut I have no idea really what it is or how to use it.
