I've made a couple of posts about issues I have been having with my tank. Here is the background:

I, not knowing any better, changed my filter media. This caused my tank (which is well established at over a year old, and has always been healthy) to start cycling. I realized I had an issue because of my pleco's behavior, and from some searching, I found you guys. I was advised to do a 50% water change immediately and one the next day, and to get a good test kit (liquid reagents, not strips).

I did a 50% water change immediately (Tuesday night), bought a test kit on my lunch break Wednesday, and tested when I got home from work. I found that ammonia was off the charts high (nitrate and nitrite were also high, but not as crazy as the ammonia) and the pH was a little low at 6.4.

I took a water sample to my LFS on Wednesday evening and they tested the ammonia too, just to make sure it wasn't a fluke or a bad test or something. They got the same crazy-high reading that I did. I bought some cycle from them. Went home and did another 50% water change and added the cycle.

Thursday (yesterday evening) ammonia was still very high. I did another 50% water change and added more cycle. I tested the ammonia again a couple of hours later. It was still high!

What the heck is going ON? Is there anything else I can do to get the level down, or do I need to just keep on keepin' on? I am going to move to a 29 gallon tank this weekend - I guess that's the equivilent of a 65% water change, basically, with all of the new water I will add, and hopefully it will help to cut down on the waste factor.

Any advice on other things I should be doing? I am trying to avoid using Ammo-lock, but I am starting to think I might have to. :(
 
It just takes time and water changes. I am in a sort of similar boat.. I cycled my tank, and put 4 fish in it. About a week later I added 10 more fish, and there wasn't enough bacteria to handle that load so I got an ammonia spike and have been doing large daily waterchanges trying to keep it under control until the bacteria colony grows to handle the additional load. The good news is it shouldn't last as long as it took to originally cycle your tank.
