    At my wits end with this cycle? Desperately need advice please.

    Hi, I am cycling my sump for my Betta rack system. I am using the API Freshwater Kit. I shake the living daylights out of all the bottles before use to avoid the crystallisation. I have cycled 5 tanks previous to this with the fish food method and had no issues whatsoever. This time I decided...

    Sudden Nitrite (not Nitrate) in Tap Water

    Afternoon all, Living in South East London, I've traditionally battled high nitrate levels in my tap water. Today though, I have a rather different issue. Having just filled a 200 litre bucket ready for tomorrow's water change on my 200 gallon, I dipped a test strip in. When testing my tanks I...

    I had my water tested on Wednesday just went, ammonia was 0, nitrite was 0.25-0.5. Nitrate was 5. I performed a 30% water change on Wednesday then I have been adding ammonia and nitrite digesting bacteria every day since Wednesday and after testing today nitrate is 0, ammonia is 0 but nitrite is...

    High ammonia - what else to do?

    Hi everyone! After all the trouble I've been trough with my tank, when I finally thought it was all going to be okay for a while, this happened in my 120L tank and I've run out of ideas of what I can do to solve it. I had a read of 5 ppm (probably more) of ammonia so I instantly searched in the...

    Aqua One Tropical Conditioning Salts For Nitrite Poisoning?

    Hi all, been dealing with a nitrite spike for the last 7-10 days at 0.25ppm. Currently doing water changes everyday to try and get it down to 0 but it’s not really working atm (I’ve done another threat for that proborn). 😐 In the meantime I’ve been adding Aqua One Tropical Conditioning Salts in...

    Ongoing 0.25ppm Nitrite Problem With Water Changes

    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...

    Unusual Testing Results

    I have a planted 10 gallon tank that I have been trying to cycle for over a week now. At first I was adding beneficial bacteria to the tank, but then I got a hold of filter media from an established tank. Before I put the media in the filter, my ammonia was at about 2ppm from dosing a small...

    Question about AMMONIA, NITRITE, NITRATE

    Hey guys this is my second post and since I received so much help regarding my questions on my first post I want to, once again, come here and ask a question. So I have had my tank for over 3 weeks now with fish in it (was established prior to putting fish in through a fishless cycle with Fritz...

    Monitoring system recommendations

    I'm looking for some kind of monitoring system that will meassure eg. pH, nitrate, nitrite, temperature, tds etc. I have a TDS meter, digital thermometers in each tank and different chemical test sets to test for nitrate, nitrite and pH. I'd really like some kind of monitor or electronic tester...

    Nitrite constantly rising with no ammonia source

    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...

    Cycling my fish tank with fish in them and need help (stuck on nitrite stage)

    So I'm trying to cycle my 29 gallons with fish in them, I bought pretty hardy fish but think I got too many in there for it to cycle well. I currently have 5 guppies, 1 platy, and a spotted catfish. I recently moved them from my ten-gallon tank so it has some of the substrate from it (that...

    Molly not quite right...?

    Hi all, I could do with some help with one of my platinum lyre tail mollies. We noticed today that he is sort of floating on the surface. I say sort of because he does swim around, albeit slowly. He has his mouth partially open, but doesn't open and close it. He also isn't eating. It almost...

    Nitrite and nitrate spike

    Hi guys, I need help. So I have a 20 gallon heavily planted tank that’s been running for about 6 months. Until now everything was perfectly fine, nitrite 0, nitrates between 10-25. I can't test for ammonia because none of the pet stores around here have any kind of ammonia tests for some reason...

    WARNING to anybody relying on strips to test their water

    I checked the Amazon page for this product after seeing what looked like anomalous test results for a member cycling thier tank. The number of bad reviews complaining of inaccurate or plain ruined test strips here is very alarming to me, especially since a lot of the budget priced items tend to...

    Hi there, I recently completed my first aquabid purchase--a gorgeous big fin koi half moon male that came from Thailand. I unboxed him Thursday evening, he wasn't dead but arrived with a good bit of his tail fin missing. I couldn't tell if it was fin rot or if he was tail nipping during...

    Fishless cycle not working!

    Hi guys, Dunno what I’m doing wrong. Started my fishless cycle 2 weeks ago. Added enough Ammonia to get it to 3ppm. 13 days on the ammonia is still the same and Nitrites are low. What could it be and what can I do to remedy it? Tank is set at 28 degrees c. Thanks, Dan

    Opinions on where my cycle is?

    My readings are Ammonia- 0.25 ppm Nitirite- 5 ppm Nitrate - 20 ppm Do I need to continue feeding ammonia? Does my tank need a water change? Any advice is appreciated, thank you
