Hmmm, sorry Victor... I'm still confused. From what I've been reading this is "cycling" the tank. I put the rocks in and tossed in a shrimp (the food variety). The ammonia, nitrates and nitrites are indeed rising. My understanding is that the ammonia peaks first then starts to drop, and the nitrates peak a little later and then decline as the critters that break that stuff down begin to multiply on the rock and in the sand. After a month or so all three should be down to 0. Now to restate the light question. Are you suggesting that I keep the lights off until all ammonia, NO2 and NO3 are down to 0? i.e. in a month?
