WM40 Power Suppy
EZ300 Cell
XT300 2" Full Flow-Through Cell
IDEAL Noalox - .5oz Tube - $5.00
Anti-Oxidant Joint Compound
This electrical lubricanting compound is an essential addition to the 
maintenance of our EZ300 cells. Simply use a small amount on the 
brass connector each time you unplug the cell for cleaning and it will keep the connector free of corrosion, prevent the connector from binding and also create greater conductivity for increased performance. 
The Circulator - $49.95
This unit replaces your existing jet in seconds and transforms your jets into "turbo charged" 360 degree rotating powerhouse. "The Circulator" pushes the chlorine you are producing into every area of the pool and even reaches to the bottom where you need it the most. This aids greatly in the revention of Black Algea which grows due to lack of circulation to the walls and bottom of the pool.
