Questions about overcrowding in top fed DWC system

Thank you! @retiredoldguy Do you run clean water through your grow medium or pretty much leave your setup intact and let the pump do the work?

@Matryoshka …I use my stick pump to pump out any nutrient water in the reservoir, I don’t pump in any fresh water without nutrients , then I use the same stick pump to pump in my fresh nutrients. I have a access hole in the top of the reservoir that I stick the pump in so I do not need to move anything.
