Hi i am not a newbie to this hobby, but i have been having some severe trouble cycling this tank. it has one angelfish in it, but i don't want to switch to fishless right now. you see i went on vacation in mid august and came back to havoc in my tank, multiple fish were dead, all the others were sick. sadly Mr. Angel was the only to survive the disaster. my ammonia has been high since then and it seems as if all my bacteria are gone. right now i have a ammonia of 1ppm but a pH of 6.2 so i guess its OK. i have no nitrite or nitrate. i have obtained filter media a few weeks ago from a friend but it hasn't helped. i am thinking of trying tetra safe start, i have heard good things about it. any help at this point would be greatly appreciated.
