Today is day three of no Ammonia,Nitrites or Nitrates.i added some more ammonia just to test to see if the tank has cycled.I planned to to get a protein skimmer and an r/o di unit when I got my tax return.I did not count on my tank being cycled so quickly since I started with all base rock and needed to make it live and do a fishless cycle.I plan on checking levels again for the next few days but if Ammonia and Nitrites are zero could i add fish w/o any other biological filter except the lr or would I be better off just adding ammonia until I get the protein skimmer and other minor equipment?
