I just finished building most of my water box 110.4 stand. It was a horrible experience with terrible instructions. It needs better instructions with real pictures and it took hours to build. Once I figured out how to put the little bolts in and align then in the rails it went faster. Stand was tightened down and seems sturdy but I have not put the tank on yet to fill and test and see if i sways. Supposedly WB can send you a kit to strengthen it. What I would like to know has anyone used the water box control boxes they sell for the tanks. Which one will work the best for all the wires/plugs? I have hand controllers for the skimmer, heater, wave maker and pump.
