Hi all, I just now registered and I'm still having trouble navigating the site so please forgive me if I posted in the wrong place! I have some questions about my use of TSS+. I keep seeing conflicting information all over the place. I originally joined on another site but people stopped responding to me there, so I'm still hopelessly lost. I have a male betta, alone, in a heated, filtered 3 gallon tank. No live plants, just some fake ones, and him. Unfortunately I am not sure of the water temp as I don't have a thermometer yet. On 6/18, I got a bottle of TSS+ and added in about three capfuls. I know the directions said to dump in the entire bottle, but it was $22 and I didn't want to use it all in one go. The filter was running and dechlorinator was added 24 hrs beforehand. After I put the bacteria in, I went to the store, brought the fish, and put him in. I know you're not supposed to test the water for a while, but I was suspicious and curious and was doing it for the health of my little buddy. I tested the water later that night (6/18), and my results were: Ammonia: 0 ppm Nitrites: ~.25 ppm Nitrates: ~20 ppm It seemed to me like the tank was cycling. I went to the other website because my tank was smelling weird and I wanted to know if the bacteria was causing it, but that's not my main concern right now. After I posted those water parameters, people on that site told me to go ahead and do a 25% water change because of the high nitrite level and because of the small tank size. I resisted, because I had read that you're not supposed to change the water for around 2 weeks. A day or two after that, I tested for ammonia, and got readings that seemed to be around .25 ppm (it was hard to tell the difference between the 0 ppm color and the .25 ppm color). I ran out of the test strips I was using for the nitrites and nitrates so I wasn't able to test for those until later on that day. When I did, nitrites measured 0 ppm and nitrates measured about 20 ppm. So my readings for 6/21 (3 days after adding TSS+) were: Ammonia: ~.25 ppm Nitrite: 0 ppm Nitrate: ~20 ppm After that, I was startled by the sudden ammonia readings. My fish was acting perfectly fine, but at the urging of the other forum, I did a 25% water change. I measured again later that day (still 6/21) and the water parameters seemed to stay exactly the same. My questions are: -Are the ammonia readings I'm getting, ammonium? I've read in several places that the ammonia readings I'm getting are a non-toxic form of ammonia, and nothing to panic about. -If it is not a fake reading and it is actually ammonia, did the cycle break? Is it ruined? If it is, should I add more TSS+? The ammonia readings started showing up before the water change and the readings stayed the same after the water change, so i don't think the wc disturbed anything. Thanks for any input!
