Now, I had another topic on fishless cycling, and someone told me to put my 10 gallon filter on my established 29 gallon tank for 1 or 2 weeks. I was also told to add filter media from my 29 gallon tanks filter. My first question is, what exactly is filter media? I have an aquaclear 300 on my 29 gallon tank, and a whisper filter on my 10 gallon.
Now if I was to do this, how would I test my water when I put my 10 gallon filter back on the 10 gallon tank? Would the nitrites and ammonia rise?
Thanks.
