So took delivery of 100 gallon Bilt Rite steel tank (Mexico, not China), 12 v pump, auto filler nozzle, hose. Welds actually look pretty decent. Now just have to get filter assembly and associated piping. See that some folks have no filter, others one, and some others 2 in series. I was looking at Goldenrod system with 10 micron filter and water " blocking". if the one filter does both, do I really need a second filter? 2nd filter would also be 10 microns. And which order to put filters in? Pictures to follow if this #%**%@# rain ever stops.
