Running at the % needed to generate the chlorine needed does not lead to
premature failure.
It depletes the cell of the chlorine capacity that was bought.
Buying a small cell is false economy. Initial cost is lower but replacement comes sooner then a larger capacity cell.
A T-3 cell is specified to have a generation capacity of 193lbs of chlorine while a T-9 is 354 and a T-15 is 580.
Polytecpools prices for cells are:
- T-3 - $430 or $2.22/lb CL
- T-9 - $679 or $1.92/lb CL
- T-15 - $899 or $1.55/lb CL
Using the T-15 cell is the clear winner at a cost/lb of CL 30% less then the T-3 and should last three times as long.
