I have a 125 that I set up a few weeks ago. I put an established cannister filter on there and started the fishless cycle. I got impatient because I saw some fish for sale that I wanted to put in there, so I added BioSpira on week 2 along with another cannister filter wich was new(no established media). One thing I noticed is that all my water paramaters(ammonia, nitrate, and nitrite) spiked. I assume this is normal and according to BioSpira, its still safe to add fish? How long does it take for these readings to come down and should I do a water change if it doesn't come down after a while or just wait it out? It's been 4-5 days now. I have my fish in there now(3 days).
