I love this site! When I first had a fish tank many many years ago the internet was still new and this wasn't available. I had a 100 gal fish tank with 3 oscars and a clown knife fish and a arawana. I unfortuanatly had to move and I had to put my tank in storage. Well over the years and countless moves later my fish tank was destroyed by careless movers. Now that I have 3 kids wanted to start up a new project and am trying to instill my love of fish onto them. I have been handed down a 12 gallon fish tank and just set it up last night! Having a little trouble understanding about all this nitrate and substrate stuff as I never did anything to my old tank other than feed the fish. Well looking forward to learning new stuff.
