Hi all, I have a soft acidic tank setup. A little background: In my original 10 gallon tank, I played with altering the water chemistry a bit by adding baking soda and got the pH up to 6.8. That probably grew the original bacteria. I am now more interested in not altering the water from my tank and in keeping fish adapted to my water instead. My main current tank is a 55 gallon freshwater tank, pH 6.2 with 1 small amazon sword, 1 unknown stem bunch plant, 1 large piece of Malaysian driftwood, 4 neons, and 1 dwarf flame gourami. Before I put the gourami in there (about 3 weeks ago) I had just the 4 neons in there - I know, not enough for a school. (I have had these fish (both gourami and neons) a while. I moved all my stock out from a 10 gallon starter tank gradually). When only the 4 neons were in the 55 gallon, I was getting 0ppm ammonia/nitrites and 20ppm nitrates. I had attempted to seed the 55 gallon with BB from an old tetra whisper filter I had on my original tank. Since adding the gourami, the ammonia has gradually gone up to now somewhere between .25-.50ppm ammonia. Nitrites are still 0ppm and now nitrates are 5ppm. I have been doing water changes once a week.The pH of my tapwater is about 6.2 (both out of the tap and in the tank). It is soft acidic water straight from our well. This is only 5 fish in a 55 gallon tank. So.. my question is - is my cycle stuck? I am wondering if the low pH has affected the BB's ability to deal with the ammonia (which is probably ammonium at this point). I do use Prime as well with my water changes. The fish all seem quite happy at this point, eating and behaving normally. In fact the neons have been exhibiting spawning-type behavior. Would it do any good to add something like TSS or ATM Cycle to this tank or would it be better to just keep up on the water changes? How do discus folks or other acidophile tanks handle cycling anyway? Thanks!
