I guess it also depends on the balance in a tank, in my case, the moderate-high fish load, automated feeding and plenty of plants seem to do well at maintaining levels constant in the tank. Nitrates are a stable 5ppm all the time, other levels also very constant, I add no liquid fertilizers, just tabs in the substrate every 4-6 months. As far as fish health goes, I've lost far more fish in my high light tanks than low light, so I'm not sure that everything we do to put the plants in turbo mode really does the fish any good in the long run.
