    High nitrates, but water changes don't help. Any ideas?

    I have a 55G tank with plants and a bunch of shrimp and fish. All my water values were always stable, but I had to put in some Nitrofurazone and API Pimafix (separately, about a week apart) to try to fix some cotton mouth on a few of my neon tetras. Now I constantly have high nitrate values...

    Water parameters

    Hi there, Quick question on water parameters. I've been reading higher than ideal levels of ammonia and nitrates and nitrites. Every week I do a 30-40% water change and the 2 tanks are well cycled around 9 months they've been set up. Question is, does keeping the ammonia levels low in turn...

    Acceptable Nitrate Levels.

    So I have seen the general advice here to always be 'keep nitrates under 20ppm'. Why? What is this number based on? Out test kits show nitrates as just NO3- ions, the studies below use nitrate nitrogen, to convert their numbers to ours multiply by 4.43...

    Hi there. Question: I’ve been fishless cycling a new 10g tank using bacteria from a bottle for about 5 weeks and why don’t I have any nitrItes yet? I’ve been feeding the tank with 10% ammonia to try to maintain 2ppm. The ammonia has been slowly dropping again and again. I have seen an increase...

    In the middle of a cycle

    Hey guys! So I am brand new to all of this! I had some Betta fish when I was younger but honestly was too young to properly take care of them. Durning the quarantine, I decided to buy one. When I did, I set up the tank how most people would think it is okay to set up a Betta tank because this...

    My nitrates dropped...

    I set up my 30g tank 3 weeks ago. I was advised to use a hardy fish as an ammonia source so I got a young bn pleco 12 days later. Although I learned afterwards that it's a bit controversial he seems to be well with good energy and appetite. Using a Sera liquid test kit 5 days ago the results...

    I have decided to start keeping fish. I have set up my tank with real plants and used Tapsafe when I added the water.

    It's been a week now that I battle with high nitrates levels in my two tanks. I know that my bigger tank is a little overstocked, so I do regulars water tests.

    Can I Use Less Water Conditioner For My Water Changes?

    Recently I tested my relatively new 29g brackish aquarium's water, and it turns out my nitrites and nitrates are both very high.   My tank's water is reading as: 7.8 PH, about 180 KH, 0 chlorine, Nitrites I think around 7 or 8, the color is brighter than my chart so it may be higher, and about...
