Agreed. At some point, the quantity of fish vs filtration capacity will be overpowered. I watched the Nitrate levels and they always stayed under 30ppm. Normally, I prefer 0-10.
But what if we were able to feed more often with the same WC and get better growth or do less WC and still have super healthy fish? Obviously WC can never be eliminated 100%. This might just be another tool to use in conjunction with overall good husbandry.
