The loss on ignition was determined by weighing the sand (or the clay) before and after its combustion at 525 °C in the muffle furnace for 24 h. The loss on ignition is given by: (3) PF (%) = m 3 − m 2 m × 100 where m 3 is the mass of the dry soil (sand or clay) after combustion (Rodier et al., 2009).

Phosphates In Your Swimming Pool: What You Need To Know

If your pool's phosphate levels are actually nearing 1,000 ppb, you might want to consider doing something to lower them a bit. One of the methods pool owners sometimes use is adding a product called a phosphate reducer, such as PHOSfree, which continually cleans the filter media and uses a rare earth metal to bind and remove phosphates upon use.
