I am setting up my system this weekend. I want to do a fill and drain system but we are a on the short side and using an IBC tank .That puts our grow beds at eye level. I want to keep the grow beds as low as possible, does that leave me no choice but to use a sump system? I wanted to use a pond pump that I already have. is there any way to make a simple float switch for a pond pump or do I need to buy a sump pump with a float switch?
Thanks
