cycle

I am fairly new to fish keeping. I acquired a free 15g fish tank, no leaks, great condition, with some healthy and established bacteria in the substrate. I have 4 Cherry Barbs (1 male, 3 females) currently in it since 03/09/19 (Saturday). The pH level is fine; the temperature is 75F. My filter...

So, here's a recap. I currently have a 20 Gallon tank with a juvenile albino senegal Bichir and a Small African Butterfly fish, and some plants along with alot of places for the bichir to hide. They used to be in a 3 gallon tank (Which after doing research, I realized was a terrible idea and...

Good morning! I have a 29 gallon tank with 3 platys; I used Tetra Safe Start. I've had my fish for 6 days, and my ammonia is steady at .5; I've done 2 partial water changes (neither of which actually changed the ammonia reading). nitrites are 0ppm, nitrates are 10ppm. I'm not sure how I have...

Hello Tropicalfishkeeping community! I am turning to you guys for infos because the people at my local petshop are absolutely clueless about what to do in my aquarium. So let's start at the beginning. I had my aquarium for many years and everything was ok, until fish started dying for no...

I got my 125g setup finally. I wanted to cycle it with pure ammonia. I have done it before to 2 other tanks in my house successfully. It has now officially been 3 weeks since the first dosing of ammonia and it hasn't dropped at all. I brought the ammonia to 4ppm and have been testing it...

I know this tank is too small and that I have made errors. Learning backwards. Ugh. Will act on the advice I receive this evening. Need to know what's best. History: 5 gallon tank that was never properly REcycled after Quick Cure killed off the cycle back in April/May. Fish were...

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...

Is this ammonia what i'm looking for? It does not bubble at all when shook. Ace® Ammonia - 6 Pack - Industrial Cleaners - Ace Hardware Thank you.

Greetings, I used Sera bio nitrivec in my newly setup aquarium. I was told to use the recommended dosage for a few days before adding fish. Is it really prudent to use 6 cap fulls(38 gallon tank) every day for a few days to get the bio filter going before adding fish? Thank you.

I've been keeping fish for 6 years now, so i like to think i'm somewhere around "intermediate" when it comes to issues with tanks. This is my first post to one of these forums, so please bear with me, as i need to be as descriptive as possible here... I was required to move, and also out-grew...

What should the ammonia, nitrite and nitrate levels be on a cycled tank?

I am getting a 20 gallon tank tomorrow. I am planning on the fish I would stock it with and how I would cycle it? My current plan for fish is: 2 Dwarf Gourami's 3 Guppies 4 Albino Cory Catfish 5 Silver Hatchet fish I ran this through aqadvisor.com and it sad 99% stocking capacity. I was...

Say you have established tanks.... how do you cycle a new tank?

So I set up my tank about a week or so ago. I know my tap water has naturally occurring levels of ammonia in it, about .3 mg/L. There are no fish currently My levels read: .25-.5 ppm ammonia .25-.5 ppm nitrite 1-5 ppm nitrate (hard to tell color) So my tank is going through somewhat of a...

Hello all, It's been a long time since I was here. I'm in the process of cycling my tank. My water is alot different from where I used to live. I'm getting back in the hobby! Anyway, tank has been running for a few days so I know the cycle is not complete yet but I decided to test the water. I'm...

Hey! Flower here. Nashville!!! So Howdy to all.... The summer I turned 19, got my first apartment. All I had to my name was a mattress, Black and White TV,and a 29G fish tank, ahhh those were the days....so I've always had a tank, until one day, about 8 yrs ago.... I just stopped, maybe the 3...

Hello. I haven't been on this site for quite a while, in fact since I bought my aquarium 2 years ago. I have a ten gallons right now, and have had the same neon tetras since I got it. I have a penguin 100 filter. My nitrite is zero, nitrate looking good, doing water changes regularly. I'm...

Starting a new Tank from fresh as I've recently upgraded from a much smaller Tank, and as I do not have the Filter media from the old Filtration unit, I have no way of obtaining my old culture (Which isn't a problem as I was quite fond of starting from scratch if I am honest). I've been keeping...
