Both are totally close loop ,fed back flush from my Sand and Gravel filter from the pond ,to the sumps, both sumps are in constant circulation and aeration ,late start ,heat got lettuce & greens ,will reinstall for fall attempt .Both sumps refreshed weekly ,excess prior to recharge is fed to ground plants ,They are going nuts! Cucumbers taken over GB ,providing shade for tomatoes and peppers and cabbage ,starting build of two compartment wicking bed 12'x3'x6" I/3 clean water Dutch bucket style .w/ perilite ,2/3 dirty water w/ soil for root crops ,potatoes ,carrots, parsnips ,etc .
