Hi, I am a new fish owner with one blood red parrot fish cichlid that I have owned for about a week and two goldfish that I got around 5 days ago. I previously had a feeder goldfish and a crayfish but the parrot fish unfortunately killed them both. The two goldfish are in a separate tank now. My recent problem is that I noticed both of their tanks stunk and that the parrot fish in particular was acting stressed, turning pale, and not eating so I decided to get a test kit immediately. It turns out that the parrot fish’s water has high levels of nitrate, with his nitrate 2 coming back with results of either 2.0 or 5.0 ppm. His nitrate 3 results came back as 20 ppm. Unfortunately, I’m a minor and I don’t have a source of income nor a drivers license yet so I have no means of buying anything myself. My dad has ordered a sand/gravel cleaning and water suction device but it arrives by Wednesday (it’s currently monday) and I’m worried that the parrot fish won’t make it until then. I went to the pet store with my mom today and we bought Prime Seachem concentrated conditioner and API quickstart but I’m not sure if it will help or not. We are in a tough spot with money right now and my parents will not let me get a big device for it just yet, but they’re willing to buy small things like solutions and anything else small that will help. Is there anything I can do or buy in the meantime to change the water or ease the toxicity? Would it be dangerous if I changed it with a bucket rather than a proper tool? Does the difference between the results of nitrate 2 and 3 indicate that one of the dead fish is decaying in there? If anyone knows, please tell me as soon as possible.
