I started my 55g on 10/3, using fish food to start the cycle. I have about 45# of marco rocks and 9# of live rock. On 10/6 my parameters were Amm-4ppm, Nitrites-.5ppm, Nitrates-0. On 10/10, Amm-1ppm, Nitrites 5ppm, Nitrtates-10ppm. Today, 10/13, Amm-0ppm, Nitrites-5ppm, Nitrates-10ppm. Salinity has remained a constant 1.026, Ph-8.4, Temp-80. This seems awful quick to be at this point in the cycle. Should I introduce additional source of Ammonia? Or, is my cycle on track and I should just leave it alone. Also, the tank already went throught the diatoms. they are clearing up now. With no light, except ambient light from the room, should I expect an algae outbreak? Thanks for the help.
