I recently transfered a bunch of livebearers from a 20 gallon to a 55 because one of the seals broke and was leaking horribly. I had no time to properly cycle the 55 gallon (which has a new eheim 2028 on it), so I used part of the 20 gallon water, collected much of the rock substrate and placed into bags and put them in the tank (55 has a sand substrate) and all plants and ornaments were transferred. I put the hang on filter from the 20 onto the 55 as well.

The water conditions in the 20 were really really bad due to small filter/over population. I had lethal ammonia levels, and the pH was dropping from the 7.8 or so out of the tap, to around 6 in the tank. Nitrates were usually very high (+100).

The new tank has been up for about 4 days. I have been told that it may not go thru the normal cycle process. The first day I tested the water and the nitrates were at 20 ppm, 0 nitrites, but ammonia was at about 3.

The second day, nitrates were at about 30 ppm, no nitrite, and ammonia was about the same.

I tested last night, and nitrates were at 80 ppm, nitrite was .5 ppm, and ammonia was at 1 ppm.

I read in a previous post that I should add aquarium salt to help nitrite burnoff. Is that correct? Should I use the suggest dose/gallon or do a smaller amount?

Does this appear to be the normal sequence for cycling? Should i be aware/watching for anything else?

I have been doing a 5 gallon water change each day (ive read not to do more than 10%). Have not lost any fish yet....
 
yes

yes

don't do water changes, or you will prolong the cycling process
 
You did good by continuing to use the old filter. Take some of the gunk from the old one and put it in the new filter. Yes, it sounds weird but that seeds the new filter and will get it in operation really fast. The little filter is working overtime by the way it is running the ammonia through the N-cycle. You must really have a bunch of fish to produce 80ppm of nitrates in four days. But that is showing you that your filter(s) is doing a great job. As soon as the new one is seeded and functioning, both the ammonia and nitrites will read at zero and you will just see the nitrates go up. Keep an eye on the ammonia (it is starting to look good) and keep up with the water changes.

Oops, didn't mean to go against you Radley. When the ammonia is high, I prefer to dilute it for the fish's sake. And yes, I agree it takes longer. It's one of those 'lesser of two evils' kind of things.
 
Yea, I know Chompers, but he is down into the "safe" range now.
 
Getting bottled bacteria might also help to speed things up, especially if you pour them over your EhFiSubstrat.

HarleyK, I see you are having problems with posting tonight as well. Is something up with the server. Bottled bacteria can't hurt, but tank gunk will be a lot better.
 
Ok so my nitrate levels dropped a little, but my nitrite is either 2.0 or 5.0, its really hard to tell the differece, are you sure i shoudlnt be changing the water???

pH levels are almost at 8 now
 
Ok its a little more clear, nitrates are at 40 ppm, ammonia is only at .5, nitrites are 2.0 ppm. Isnt that bad?

why is pH level going up?
 
That's wierd that your pH is going up. Add a neutral regulator to keep it stable.
