Welcome I'm a month into my first tank . and I'm taking it slow and reading on here every night . I have a 20 gallon with is more like a 15 gallon after you add sand and rocks . All I have in it is the sand rocks and 2 clown fish . I'm holding out as long as i possibly can before i add anything else . I also try to only run blue lights for 8 hours a day and maybe white light for a hour or 2 when i get home so i can feed them . I check parameters every few days and write them down to compare . I got Api kits but most people on here say "NO" to that , but for now that's all i can afford . Wife's been out of work for a month :( not sure if I'm doing everything right but I'm trying . If this was fresh water id probably be rushing way to much . Good Luck !!!! and take it slow !!!!
