Hi, I have come to this site for over a year now looking for answers and finally joined today. I started out a year ago this April. Literally at petco and someone walk up to me from a van (no candy (coral) though) she ask me if I liked fish and gave me a bucket with live rock and two clownfish in it also a box of salt among other things. All for free! It was crazy so thats how I got started. They are still alive and healthy thanks to my anxiety of wanting them not to suffer because of my ignorance. So here I am finally upgrading to a 20 gallon fancy with the filter all in one inside instead of a hang on the back filter. I don't know where or what to put in the back part so I'm here for help. Sorry so long. I'm not good at giving small details.
