I add the algaecide as a precaution, as there is little, if any, liquid remaining on the bottom of the tray if you have is leveled correctly.
My drain plug is similar, but I notice it has a small lip that prevents the tray from completely draining. I have tapped a couple holes and leveled it as to drain the entire tray.
I think I will have to adjust the timing a bit, but the pump compensates the drain holes and still fills quickly.
I used alot of your info in fabricating my system. I'll get some photos up as I get it situated where I want it.
I cut holes in the tray lid and the pots hang from it as opposed to setting on their bottoms. The overflow triggers at the halfway point of the pot. I can see the roots laying in the bottom of the tray once they begin running,
