librarygirl: the seeded media I got was one of those cartridges which was pretty gunky and has what I think is carbon still inside it. But what I am not sure of is what was in the tank it came from, now that you mention it! As I look back, it came from a half-filled, but running, tank. I suppose it's unlikely that there were actually FISH in there! Hmmm...the stuff was definitely wet and I even tried to keep it warm for the ride home; I put in into the tank shortly after I dosed the tank with Prime and allowed it to circulate. Now I'm wondering if I should get rid of the seeded material, I hope I haven't done more harm than good!
jlk, I am using city tap water. I have seen water quality reports in the past where all contaminant readings were pretty good, but I'll have to find out for sure when I call the water dept. tomorrow.
I redosed the tank with ammonia last night. My ammo reading after the WC and before re-dosing was 0.5 ppm. I used the calculator and it said to use 7.xx ml of ammonia. Since I already had the 0.5 reading, I thought maybe I should use less to start off, so I added 5ml which seems to have brought it right back up to 4ppm. I did this only around 9 hours ago, so I'll retest tomorrow. Thanks, everyone!
