I have been using 2 Part for many years for my 300g mixed reef. I am now growing more SPS and my dosing has increased to 350ml/day using Randy' recipe 2. I expect this to increase significantly as my SPS grow out. Are there other large tank reefers out there with big 2 part demands? I would be curious if anyone is dosing more than this amount. Or, should I be considering switching to a CO2 reactor?
