nitrite level

Hello! I got a 55 gallon tank over a month ago and I’ve been trying to cycle it using the fishless cycle with Dr. Tim’s ammonia and beneficial bacteria in a bottle. I’ve been following the instructions from Dr. Tim’s website but also referencing the forum here for more information. I’ve never...

Hi everyone so I’ve had a new tank now I had it cycling for 3 weeks until my water perimeters were okay everything ammonia and nitrite was at zero and nitrate was sitting a good level I added my fish and my levels have been fine since I did a water change a week later I’m not sure what I’ve done...

Hello All, currently on day 21 of a fishless cycle and have no nitrites as of yet. Is this normal or have I done something wrong. How long has it taken other people to see nitrites appear ? My tank is 80 litres, the filter is set up and the temperature has been at 28 Celsius / 82 Fahrenheit...

Help! My tank is cycled and has been running for over 6 weeks. All my levels have been great up until last week. My nitrite spiked at 1.0-2.0ppm. I did a 50% water change and it dropped to 0.25ppm straight away but has now been stuck at 0.25ppm for over a week. I have been doing 30-50% water...

Hey everyone! I hope you’re well :) this is my first post so please be kind! I’ve been reading so much conflicting info about high nitrites and I’m super confused. Im extremely new to keeping fish and I want to get it right! I was told by my local fish shop to cycle my fish tank for 24 hours...

After a little help here, as I'm non-plussed. I'm mid-fishless cycle with a 450l (120 us gallon) tank and my nitrite readings are making no sense to me. I started with adding Dr Tim's ammonia a couple of weeks ago, plus "one and only" bacteria. I know there are mixed views on whether it does...

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...

Tank Inhabitants: 2 baby blue shrimp, nerite snail, mystery snail Temp: 1 heater set to 86 deg F Size: 10 gallons added a few cholla wood pieces (x3) and it totally clouded my tank, including these levels: added a carbon pack, but I’m waiting on an air pump for a medium-sized sponge filter

Hi, I`m at day 26 of a Fishless Cycle of a 20gl tank, my Ammonia is getting reduced from 2ppm to 0.25pmm in less than 12 hours, my Nitrates are at 20ppm but my Nitrites are far above 5ppm and are not reducing. I have already done several large water changes during the last three days, this...
