You have made a good move by coming here and asking. I belong to several forums, but this one is my favorite. There are plenty of people here willing and able to offer good advice and not make it sound like they are talking down to you. If you have questions, this is a great place to get answers. Unfortunately a lot of LFS
's will tell you something so they can make a sale and their answers tend to be wrong. The people here are active aquarists with a lot of experence and can tell you what works, what doesnt work and what their opinions are on a lot of issues.
