'Use AmQuel+ instead of the Prime @ 5x. Just double the dose and you should be good to go. AmQuel treats the chlorine, chloramine AND excess ammonia, nitrites, nitrates.'
I've casually watched this thread from the SW corner and been concerned by some of the advice. What I can't do is let someone bash and miscommunicate what is, in my opinion, the best product on the market. That being Prime. Prime removes Chlorine, Chloramine and Ammonia along with detoxifying nitrate and nitrate. It is in many circles regarded as the best product on the market; bar none.
One person yesterday advises this person to use Amquel, today tells them it will screw up their test results.
My advice, take it or leave it, is to start with and continue large multiple water changes to keep the toxicity down. As you continue to test DAILY (or more often) watch for the cycle to start to mature, then lessen the water changes so the cycle can pick up steam. Slowly moving back to less and less water changes. Use PRIME or any other product that you prefer to SPOT TREAT high results. The products will help you deal with spikes but use water changes to keep things in line.
Go back to your LFS and BEG AND PLEAD for any used filter material to help get you over the hump. Buy it if you have to. Shove it in your filter or at this point just throw it in the tank.
If your fish don't make it then while it's sad hopefully you've gathered some knowledge that will help you through the next one. Three of them being: 1) Fishless cycle 2) The cycle is what it is. There are very specific ways to determine where you are in it and when it is over. 3) Chemicals (except for dechlor) will generally come back to bite you so stay away from them.
