    To effectively practice the TFPC methods, the FAS/DPD chlorine test is essential. All these kits contain that test while very few other kits do.

    PoolMath, http://www.troublefreepool.com/calc.html, is a handy web-based tool that does all of the calculations required to maintain your pool. PoolMath can figure out the amounts of chemicals to add, what appropriate FC levels are for your CYA level, what your calcite saturation index is, and help you estimate your pool volume. It is also possible to make a local copy of the PoolMath web page, and use it without an Internet connection.
