#92###, The OP did a fishless cycle, you'd think that he/she had killed someone the way some of you go on.
Personally I prefer fish in cycles, pet stores use, it and so did hobbyists before people actually twigged about using ammonia instead of fish faeces, short term exposure to ammonia and nitrite, may <<<< MAY harm the fish, there is no solid evidence to say it will, it depends on the fish species, the water temperature and the PH of the water, seriously, stop shooting the guy down, a fish in cycle is a totally acceptable way of cycling a tank.
My objection isn't really the fish-in cycle, it's the attitude and the way it was handled - unless I am very much mistaken, the OP allowed the nitrites to sit at an elevated level for around two weeks.
A "may harm the fish" is, in my book, as good as a "will harm the fish". It's a living creature and we shouldn't be gambling with it's health if it can be avoided.
Now, if the OP actually meant he tested the water at least once daily, got levels of 0.25 and then did a very large water change (according to fish-in cycle 'best practice') and this continued for two weeks, then that's all normal. However, that didn't come across in the post.
I'm not knocking a fish-in cycle. They are often necessary. However, convinience is a poor excuse and the fact that fish stores and old time hobbyists do them is definitely not an excuse. People also used to regularly dock the tails of dogs, but we don't do that without a valid medical or working reason anymore.
Ignorant reply I see.... convinience is a poor excuse? Do you own a dog? Do you have it fixed? if so thats a convinience! And I guess in your terms mentioned above that fixing a dog is definitely not an axcuse! After all it is for convinience so the dog doesn't get knocked up etc. .25 is not a killing amount nor means he should be going to jail! Some of you need to grow up we all know how a cycle works by now, not to mention the plants helped in keeping the ammo and other stuff down zzzzz

I put fish in as soon as the water is up to temperature!!!!
I have not done a water change for 8 months!!!!
I add nitrate and phosphate if I need to and will add excess if I want to!!!!
I will add CO2 to a very high level without fear of killing fish!!!!
I have nearly 20x the tank volume in circulation without fear of blowing fish away!!!!
I use excessively low amounts of light to achieve heavy growth!!!!
My fine sand substrate is over 3 years old and is not cleaned or stirred!!!!
I ignore the 'tolerant temperatures' that are given for each particular fish. Between 22 and 28 suits all the fish I ever had
I think he summed it up well! I have 4 discus and they cost 100 dollars each now, I never cycled my tank when I set it up as a planted tank, I keep temps at 82-86, I keep very temp sensative fish (Cory's, Kuli Loaches, Snails, Oto's) and they have been living in that tank for a long time now(2 years now) and all fish are healthy and stong! I dose Nitrate in the tank and discus are sapose to be sensative fish! I do water changes I add warm water to the tank! I forget to do water changes from time to time(It explains my algue I get) I double dose on a rest day! All this against all your rules yet my Brazil sword Has flowered not only once but twice in a season! Go ahead and ask around its the rarest flowering you will ever get to see!
I think the op did a good job, although he ran into some issues for the majority of it he lost 0 fish! You all need to look into things with a mind wide open! It is not a 1 rule suits all world! Many planted tank hobbyist don't even follow rules that are set out some might take a rule here and a rule there but for the most part of it none are actually followed! This applies to cycling as planted tank hobbyist don't even bother to cycle a tank! So keep in mind you buy that doggy in the window don't bother giving it shots or even getting it fixed cause you would be a hypocrit on what you stated about this individual!
BTW I own 2 dogs 1 is fixed its a male the other is not fixed its a female and I won't bother fixing the animal its to much money and I don't need an excuse(getting her fixed would eliminate the excuse)to not have her fixed! Its easy for me to regulate when she is in heat on who she gets to hand around!
Everyone grow up and have a wide open mind!
