In the FAQ section under hydro, should I top off my reservoir, its explained that an ideal situation would be to add a nutrient free res. like a trash can with shut offs, inbetween the water filter and your nutrient tank. Why?? Or rather, why not run auto shut off from the filter straight into the reservoir? What is gained with the intermediate tank, other than emergency water storage?
