Hi,

This is a sad first post I know but I need to know if I did the righ thing as I'm very concerned for the well being of my fish >.<

To start I got a 20 gal tank for my 29th bday on feb 24th. I set up the tank and was verry happy with it and did not have any fish at all for a week. After the first week went I got 3 white cloud minnows (love them so much) and was going to wait untill the entire cycle was done before adding any fish at all.

The problem Starts because my fiance thought I would really love to have the rest of my fish as the second part of my b-day gift so she knew what fish I wanted and how many I wanted in my tank and while I was at work went to the LFS and bought 6 more white coulds (damn pet store gave her 4 males and 2 females totaly messing up the ratio I wanted of 3F/1M) and she got 12 Blue neon tetras (LFS again messed up marked them as neon tetras but they compleetly lack the red of a neon and are just silver with a blue stripe). Thus I came home to the suprise and could not be mad or angry as this was a suprise/gift but inside I knew my fish would suffer due to this :(

So what I did was keep a close eye out on the amonia and I was able with daily water changes (sometimes 2 small changes in a day) to keep the amonia levels at a acceptable level but I knew it needed and was going to peek out so didnt do any drastic water changes all of them were small 10- 15%.

Then at the beginign of this week my nightmare happened! I came home from work and all of my tetras were loosing there bopyancy capability....like they were going belly up and jerking to get back on there belly. So I panicked and took out 50% of the tanks water and then added tap water but I used chlorine & chloramine remover in the watter but im sure I added the water in before the remover took affect. The problem was I either waited longer for it to take effect and watch fish suffer/ or die, Or I added it right away and stressed them out and hope for the best :(

I went with the lesser of 2 evils and am happy to say none of them passed away and came back to life in about 20 mins!

My main problem now is that its been about 6 days now and the nitrite levels are still at about 2ppm and I am doing daily water changes of about 20% to make sure the fish dont pass away due to it. My nitrate levels have started to come up in the past 4 day from 0 to 10 and the amonia is at 0 so I know the cycle is starting to come to its end but my fear is that I may have messed it up or killed off bacteria with the mass water change...


Did I do the right thing and about how long do you think it will take for the nitrite to go down?


***Let this post be a lesson to anyone that was thinking of getting some one fish as a gift! If you want to give them fish either A) go with them to a LFS or B) get them a gift card so they can get what they want when there tank can handle it!***

Once you add declorinator to the water it instantly removes the chemicals.
Just keep up with water changes.
Dosn't sound like you have long to go.
 
Daily 50% water changes will sort it. Don't worry about this causing stress - it causes far less than the nitrite will!

Feel free to use some hot water so you're not constantly hitting the temperature, especially if your heater isn't overly powerful.
 
Hi twin54.
Welcome to the forum from a fellow newbie! (oooh...not realised I'd gone up to fish fanatic :hyper: )

Edit: just realised I took so long writing this reply that 2 people alread beat me to it & in much less writing :rolleyes:
oh well...

I'm definitely no expert, but can regurgitate a few bits of info I have found on here time & time again that might be of some help.

1. The beneficial bacteria that break down ammonia and nitrites live in your filter media & some on objects in the tank, so changing the water won't harm them if they still have a feed source (fish pee etc). (&as long as dechlorinator went in at same time as water that should be ok too I think)

2. I don't know how long it will take for your cycle to finish (sure someone else might though...) but as I understand it, very regular (like daily) water changes during the fish-in cycle are the only way to control levels of ammonia, nitrite and nitrate and hopefully keep your fish alive.

HTH in some way (apologies if anything incorrect, someone more knowledgeable please correct me :unsure: )

So again today after daily 15% water changes I tested teh full range of my water...

Amonia... 0 YEAY
Nitrates 20 :S time to do a slightly bigger water change!
Nitrite : 1 :( still is not going down :( Wondering if I should do another big water change of say 60-70% and se if it will help level things out :S I deff knwo the amonia eating bacteria are set in place just looks liek the nitrite eaters are taking thre sweet time :(
 
I wouldn't do such a large water change. Only do 50%.
 
From all accounts the Nitrite noshing bacterias take longer than the Ammonia ones - mine did.

20 Nitrates is not bad, you should not worry about this number being high compared to Nitrite as Nitrate isn't as toxic to fish, 30 is considered getting high though and anything larger is normal sorted by a weekly water change anyway.

Continue daily 50% changes until you see Nitrites at 0 then monitor daily.

I did say do 50% daily changes! Try it!

Don't worry about Nitrate. Its probably in your tap water anyway

Been a while since I replied here but thank you all for the help! I now have my 43 galand 20 gal runing at 0 amonia, 0 notrites, and keeping them @ or under 10 nitrates! Thank you all for the help :)

No problem - glad to hear you got the tank under control - hopefully you didn't lose any fish.

Came close to loosing all the neons a good 9 times but did emergency water changes each time! I have lost a total of 2 fish since I started! 1 was a neon that was too small and got sucked into the filter :( I used some of my fiances old pantyhoes and a rubber band to fix that till they got bigger, and the other fish was a pacific blue eye that died 3 hours after takign him home however the other 5 are alive and well! Sucks I lost thoes 2 but I have tried my best to make sure all my fish are healthy! :D
