  1. Did a Test for Water Levels, now what? nitirite is high

    Beginner Freshwater Aquarium
    gh - 60 kh - 120 ph - 7.0 nitrite - 1 nitrate - 40 I read on the forum that the nitrite can be caused by overstocking or over feeding. I might be over feeding, but the endlers seem to eat every little bit I give them. I just did a 20% water change - first time in a few days. I use to do a...
  2. Low Ammonia - HIGH NITRITES - Happy Fish?

    Beginner Freshwater Aquarium
    Started a new 20-gal freshwater tank 14 days ago. Went fishless for a few days, trying to jump-start the cycle using Nutrafin Cycle and some fish food in the water. Saw about 0.25ppm of Ammonia consistently for about four days. No measurable Nitrites, but 10-20ppm of nitrAtes. I'm using city...
  3. Ammonia going down but no nitrites.

    Beginner Freshwater Aquarium
    I'm in the process of cycling my 20 gallon tank and the ammonia levels have steadily been going down, but there have been no nitrites whatsoever. Right now my readings are 0 ammonia, 0 nitrites, & 5 nitrates.
  4. Nitrate spike

    Beginner Freshwater Aquarium
    Just checked my water today and discovered my nitrate is at 80ppm nitrite is 0 and ammonia is 0. I'm guessing a water change is needed? Why so much nitrate
  5. The Nitrogen Cycle

    Beginner Freshwater Aquarium
    Welcome to another episode of Aquahound's Dirty Little Secrets! In this episode I explain the Nitrogen Cycle aka "The Silent Killer" which is one of the most misunderstood topics in the fish keeping hobby today. Every new tank goes through this cycle and it is important to understand how and why...

    Beginner Freshwater Aquarium
    Hi guys, I've been cycling my 56 gal freshwater tank and it seems to be stalled. Could you please look at these parameters and tell me what you think? 4/20: filled the tank with tap water, added Amquel to remove chlorine and chloramine. Added seeded media from established tank. Ph reads at...
  7. Nitrogen Cycle Question

    Beginner Freshwater Aquarium
    Hi this is my first post so hopefully I'm not asking something that's already been answered. I have been cycling a 55 gal tank for a little over a month now and everything seemed to be going ok, I am using 8 cherry barbs and 1 small plant. The ammonia went up, then came down as the nitrite went...

    hello everyone. I have brought a new fish tank on monday. It has been set up for three days with everything in it including the filter, the heater etc. I have washed all the ornaments but the water has gone cloudy, not on the surface but all of the water. I tested the water and the amonia is...
  10. Nitrite reading confusion!

    Beginner Freshwater Aquarium
    My first tank (20gallon) seems to be nearing the end of cycling. As of ten seconds ago: Ammonia - .25ppm (*happydance* it dropped from yesterday's reading of 1) Nitrate - 20ppm pH - 7-8 (I haven't tested it in a few days) Problem: I cannot understand my nitrite reading. It's this purple color...
  11. need help with Nitrite and Nitrate

    Water Chemistry
    Are my levels ok or can I get them down lower? I have been fighting with my nitrate and nitrite since I have started my tank about 6 months ago. I cant seem to get them any lower. Algae doesn't seem bad. I am doing a 20% water change once a week. I have read that if I remove the bio wheel from...
  12. Sick Yellow GloFish & Nitrite Problem - Need Advice

    Beginner Freshwater Aquarium
    I have a tank of four zebra danios, one being a Yellow GloFish. As of the last two days or so, he's been looking pretty sickly. He only swims to the top left and right parts of the tank, and seems to stay there all day - he never socializes with the other fish. The other three regular zebra...
  13. New Tank and maybe sick Mystery Snail

    Beginner Freshwater Aquarium
    Hello, I have a 5 gallon Tank that I've had for a month. The Nitrate is borderline and Nitrite levels are high. I am wondering if this is from the beginning of the nitrogen cycle to create the bacteria. I am very new to this. The aquarium has 3 danios and a mystery snail. The...
  14. 29 gallon tank still not cycling after 5 days

    Beginner Freshwater Aquarium
    Hey, I got a 29 gallon tank for Christmas and set it up the same day. I had heard about fishless cycling before, but I have never used it. I put fish food in to put in ammonia and turned up the heat to about 82 degrees F. I didn't leave the light on, but I turned it on today. Today I got back...
  15. New 30 gallon cycling journal

    Beginner Freshwater Aquarium
    I thought I could post this here, since this is the first time I've cycled and would like advice. I've been putting fish food in my tank everyday cause I think it helps it a long a bit? I've also taken the dirty filter cartridge from my 10 gallon and put in the new filter device in my cycling...
