Well, I'm now on day 14 and my readings are: NH3 - 0, NO2 - .5, NO3 - 30. I'm guessing the tank is getting close to being cycled and I'm thinking about adding a clean up crew for the large amounts of algae and diatoms that have formed on my LR, glass, and substrate (I vacuumed it out a few days ago, but some is growing again). What critters, and how many of them, would be a sufficient crew for a 72 gal tank? Thanks for all of your help.
