Greetings.. Newbie here to the forum. Ive had tanks before stopped with the hobby and then started again. Recently I bought a 75g and a 10g as a q tank. The 75 I dosed with maybe 3 ppm ammonia. That was almost four weeks ago. At about day 12 I read nitrites at about .5 - 1. The next day they were gone, but there were no nitrates. That was about two weeks ago. I still have no nitrites or nrates. Ammonia did dip a little but not much. Any idea what happened? They obviously appeared, but literally next day vanished? Question 2, the 10g I dosed with 1 ppm ammonia and figured I would experiment for kicks with tetra safe start. After almost two weeks ammonia is dipping a bit but no nitrites; however I am showing nitrates are starting. Tested my tap to make sure. Is that normal with t.s.s. I only tried tss in the 10g to experiment..thanks in advance. Sorry so long of a post.
