Such dedication. Cleaning your filter at night? lol But I can see your point. Doubt I could talk D into doing that though. And it would be difficult to clean half at a time unless I had vertical pads like a beehive to pull out. Unless you mean to only pull half the bags of rock. I ordered extra bags a long time ago. Have divided rock into six bags. The two they sent would have needed a crane to pull them up. They get pulled in the fall, washed, then laid on some pallets by the pond with the matts covered with plywood and poly. Obviously need recharging in the spring.
