Yesterday evening I did a 15 gallon water change. That's almost 30% of my tank! My nitrates before the water change were right around 40 and this morning they are at 40ppm. My nitrates in my old tank, 26 gallon, would stubbornly hang around 20 but never like this! More water, more rock, less horses.... The only thing I can think of is that I don't yet have as much macro in my new tank is that the problem? Can I do another water change today?
