LMTC Swimming Pool Potash Alum/ Potassium Aluminium Sulfate (Tawas Crystals) (1 KG)

1-9 KGS - PHP 78 EACH KILO 10- OR MORE - PHP 75 EACH KILO Alum, short for aluminum sulfate, is a flocculant, meaning that it attracts and traps suspended particles in the water and then sinks them to the bottom of the pool so that these particles can be vacuumed out. Quite often after using alum most pool owners will find the water to be crystal clear with the exception of a solid layer of the chemical and particles on the very bottom of the pool. The use of alum is more labor-intensive but often gives quick consistent results.
