Great idea with the dye test Xcrispi!! I'll try it....sounds like I won't need to mess with the "T"s though...20 mins to recirculate each bucket sounds fine. I'm only going to use 4 buckets so it should be good and I'll use the Via Aqua 302 as you both suggest.

Also, elevating the buckets and the res but not the recirculating bucket also sounds like a great idea Bud Luv.

Why do so many people not choose to use the WF Res/Contoller combo??

Thanks for all the helpful advice for this hydro n00b.
