SenDep tank still progressing.will complete insulation panels for the basin ( in this photo) in next 2 days. Then on to the cabinet :-) Module build requires a big more planning and better execution but it's keeping the project from seeming too daunting.
Finally finished with the making of four 12ft signs for neighborhood and working on the NEW DIY Sensory Deprivation Float Pod. Here is the plumbing cabinet completed except for doors and outside finish. The yellow pump is a magnetic drive pump and it pumps water from the lower float tank into the tall filter tube which is a triple capacity mechanical filter. From there it flows into a Balboa spa heater controlled by a controller with 1f accuracy. Heated water then goes through an Ultraviolet light sterilizing unit and through a Venturi than adds ozone via corona discharge unit and finally back into the tank. The whole cabinet sits on top of the float tank so that any leak or system failure will drain directly back into the main tank without drama of flooding the room as happened in my old pod. I never want 900 lbs of Epsom salt with 150 gallons of water on my shop floor again :-)
This tank is designed to be narrower than most. This allows the floater to center just by letting hands splay out enough to touch the sides and stop the movement side-to-side. On wide tanks the movement side-to-side can be quite a distraction waiting to be able to top the side and stop. This also provides a smaller foot print of tank and less water and salt to fill. I'm 6 ft and 220 and fit with plenty of room for comfortable use. Inside dim is. 88" x 39" x 13" deep for a 10" water line.
