Okay, so I set up a 20 gallon tank at the beginning of November. I intended on using it for quarantine and then use the cycled media to set up my 90. I had a few cycled tanks running before about a year ago, but had to move and start over. So I cleaned an old AquaClear 50 (soaked it in vinegar and water and rinsed well and dried it) and filled it full of those little biomax pellets and set it up in a totally empty tank. I added enough pure ammonia to get the count to 2ppm and left it alone. About a week later I checked the ammonia again, and it was a super dark rating, almost black. So I changed the water and cleaned the tank as best as I could and got the ammonia to about 1ppm then left it alone again and about 6-7 days after that checked again, and again super dark ammonia. Thinking my test was faulty I went out and bought a new one, tested the water again, and it had the same reading as my original. So basically I went in a loop, checked the water daily for ammonia and changed it when it got to about 4ppm which was probably every 5-6 days or so. No nitrites or nitrates showed up at all. I asked for help on another forum about two weeks ago and they didn’t have much to tell me for help besides to get one of those bacteria booster things and I hadn’t heard much good about them so I had never used one before but figured I had nothing to lose by trying so I got Seachem Stability and used it as directed for a week. As I used the Stability nitrites and nitrates started to show up. I wasn’t sure if my cycle was going anywhere or if it was just the stability. Ammonia was still going up, but now nitrites we’re going up super high too. A week after finishing adding stability my water is currently close to 4ppm ammonia, close to 2ppm nitrites and 10ppm nitrates. Nothing goes down, only up, it has slowed the ammonia growth but not by very much. I use prime as a water conditioner, and my tap water starts off with 0.5ppm ammonia, 0 nitrites and 0 nitrate, the ph is about 7.8-8.0. The only thing I can think of that’s adding any ammonia to the water is the cats drinking out of the tank, but my old tanks had cats drinking out of them without this problem and it’s driving me crazy now. I just want some fish! It’s been nearly 3 months.
