When I first rescued my Jack Dempsey, almost a year ago, he was very ill and I had to keep him in a ten gallon tank. (I was a new fish owner and never could get my levels to 0 or close to 0) Then after a few months, I bought a 55 gallon tank and cycled it for a month and a half. Then I acclimated him, and everything was great. My levels at that time were close to 0. I would do regular 10% water changes once a week. At the end of Summer, my roommate and I decide to clean the gravel, but we ended up taking out half the water. Then that's when things started to go wrong. After that it was a constant battle of trying to bring my nitrate levels down. I did the same amount of water changes every week, but nothing was changing. I could notice it in my fish, he was very stressed... When it got really bad, he would get fin clamp and barely move. So I found this product called nitra-zorb. And it worked so well! All my levels went back to 0 or close to 0... But as soon as I took it out after a week or two, my nitrate would skyrocket! And I didn't have the money to keep buying nitra-zorb every two weeks... So I stopped and just stuck with my water changes and gravel cleaning... Then it came to a point where I was doing more frequent water changes or changing out a little bit more water once a week because my fish looked so unhealthy. And I've noticed when he's stressed he gets almost clear feces. But he would still eat regularly. Then one day a few weeks ago I started to notice the ammonia spiked. It was 0 this whole time or close to 0, but now it's at .25. Then I watched a video on how to break down and clean my filter and did so. When I went to plug it in, it stopped working... So I mailed it back to the manufacture for a new motor... I was panicking for my fish, so I went out and bought a more expensive filter (maybe mine is not a good enough filter?) and the new filter is great... Except my ammonia and nitrate levels were high, so I bought another nitra-zorb thinking that would be a quick fix. (In the back of my old filter, it was small, room for two filter pads so I had room to put the nitrazorb... But my new one, has four filter pads and I barely any room to put the nitrazorb so I took one filter pad out and put the nitrazorb in its place...) And the levels are higher then ever? I feel like I'm losing my mind! So I called the nitrazorb customer service for some help, and they told me everything I already knew... My levels are now as followed ammonia- .25 and nitrate- 50 to 100 I'm not too sure. So I'm out of options. I don't know where to go from here. My fish is so stressed and the last few days it's been hard for him to eat. Out of this whole process, he's only not had an appetite in the first few weeks I had him and that's because he was really ill. Does anyone have any ideas or suggestions? I'm desperate and am almost wiling to pay someone to come to my house to see what's going on...
