Using PHOSfree a Step by Step Guide
Treating
high phosphate levels in your pool is easy with Natural Chemistry PHOSfree and
anyone can follow these simple steps. It is important to follow the steps for
the best results. Below are the step by step process of using PHOSfree in your
pool.
Directions
for use of PHOSfree:
This
product is designed for use in properly balanced pool water.
1.
Clean or backwash filter.
2.
Determine the appropriate dose. * See chart below.
3.
Shake bottle well prior to application. With circulation pump running, add a dose
to the skimmer.
4.
Run filter for 48 hours continuously without backwashing or cleaning.
5.
After 48 hours of filtering, clean/backwash filter. Retest phosphate levels,
and if necessary, repeat steps 1-5.
Note:
If DE filter pressure rises to 10psi above start-up pressure, turn the pump off for
1 minute and then turn it back on. If the pressure remains high,
backwash
or rinse for 30 seconds.
Dosage
Chart:
Dose
per 10,000 gallons (38,000L)
Phosphate
Level PHOSfree Dosage
300ppb
or less 0.5L or 16oz
600ppb
1L or 32oz
900ppb
1.5L or 48oz
1200ppb
2L or 67.6oz
For
DE & Cartridge Filters: Do not add more than 1.5L (48oz) at a time. If more
than 1.5L (48oz) is needed to treat, be sure to clean or backwash
the
filter between treatments.
Important:
Algae must be treated prior to testing and lowering phosphates. Chlorine must
be under 5ppm before testing phosphates.
Make
sure you adjust the dosage based on your pool size. Adjust the dosage up if you
have a larger pool than the 10,000-gallon base chart and adjust the dosage down
if your pool is less than 10,000 gallons.
Keep
in mind phosphates are measured in ppb – parts per billion instead of the
standard ppm – parts per million used in the industry. To give you an idea of
how small a ppb is, imagine a roll of toilet paper stretched from New York
across the Atlantic Ocean to London. 1 ppm would be one tiny sheet of the
entire roll that is stretched across the ocean! So a phosphate level of 100 ppb
is extremely minuscule but any amount of phosphates in the water is food for
the algae. We are dealing with the microscopic world in your pool and strangely
these very small amounts can destroy the pool’s chlorine level and cause algae
to bloom on the pool surface.
There
are of course factors that contribute to algae in your pool. The main factors
that I see are poor filtration, not running your pump long enough, flow issues
due to air leaks in the system and improper chemistry – low chlorine levels
each week. After addressing these issues, you can still get algae in certain
areas of your pool and attached spa. That is where a phosphate remover like
PHOSEfree can come in handy.
