The ammonia has now gone back down to 0. It was either an incorrect reading or it was a slight blip - I had fed the gobies/inverts so maybe that pushed the ammonia up slightly? Why the drastic water changes? I'm not aware that the tank has really cycled or if it has it has only taken a matter of days to go through ammonia/nitrite/nitrate. I thought the live rock was there to help with the water quality? I also read somewhere that in the early days with the biorb if you change too much water etc if affects the bacteria colonies and makes the cycle take longer. Also, the filter is a non-sponge one with resins only and to change it you actually have to replace the whole thing. Changing it every fortnight is going to be very expensive and it is also not going to be that easy to move all the rock to get at the filter too often. What does JMO mean?! Also, could you give me any indication of the likelihood of my mushrooms thriving? The light does not support photosynthetic corals. Many thanks
