Update!!

Hello everyone! I am VERY happy to say that my tank, after two months and many, many water changes, is finally cycled. I've got 0 ammonia, 0 nitrite, and 5-10 nitrate. The six danios I had during the cycle all made it through and seem to be fine. I'm sure they are enjoying the healthy water, finally. My only problem (and it's a small one) is a bit of a type of brown algae. I forget what it is called but it comes off of anything very easily. I'm not sure if it is going to get really bad or not, I certainly hope not.

Should I allow the cycled tank to sit for a while before adding a couple new fish or am I safe to do it now? I'm really looking forward to getting some new faces in the tank. Thanks to everyone for all the help!!

Congrats! I am still waiting for nitrItes to show up, and it is 10 weeks in..... I have brown algae as well, and I was told that it will go away with time. I believe that it was caused from excess ammonia.

Congrats!!! Always a good feeling to see your tank has cycled! I think if your ammonia and nitrites stay 0 for 2 days without water changes, it should be safe to add 1 or 2 fish.

i dont know how big your tank is, and granted you only have the 6 danios i think its safe to say to SLOWLY increase the number of fish you have over a period of weeks.

I agree with what has been said. As for the algae I would just scrub it of before it gets too established. It can be a pain so getting it off right away is probably the best option. Just so you know brown algae is quite common in new tanks.

the brown algae is not algae as we understand it, it is a diatom bloom, it is feeding on the silicates in the tank. it will run out of nurishment soon and disappear completly, you need do nothing & in fact there is little you can do. it sounds like you engaged in a cycleling with fish, this is very cruel treatment for our fish friends, fishless cycling is the way to go. 2 months to cycle a tank is way too long, avg is around 20 days.

without knowing the capacity of your tank it would be foolish to recommend you add more fish. your setup and filtration are also deciding factors.

I'm sorry, but 2 months is perfectly fine for a cycle. As well as Diatoms are algae (most commonly seen in SW) and will go away eventually. And cycling with fish is fine as well, when you do water changes like Blissfulfish said they did.

And they have a 20G. Found out if a search was done.

Anyways,

I can't wait to see what you will do with the tank. It looks great so far.

An aquarium book that I have says that as a general rule, cycling can take from one month to 6 weeks but that the timetable depends greatly on the unique characteristics of t he aquarium and its inhabitants.

Rugie-

From what I have picked up on, most people who cycle a tank with fish are just getting into the hobby(like myself) and do not know any better. I will never again cycle a tank with fish, but I bought fish for my 30 gallon before even knowing about the nitrogen cycle. Please do not get upset with newbies who cycle their tank with fish, most of them do not know any better until they come to this forum because one of their fish has died. I am thankful for the people on this forum who do not pass judgement on people and try to help us.
