Pool & Spa

High Phosphate Level

Phosphates in the pool and spa water can cause a variety of water quality issues, including clouding. If you suspect phosphates may be the source of your water quality issue, it is always best to have your water tested. Treatment can only begin properly when the level of phosphates is accurately determined. Phosphates enter pool and spa water from many sources, which is why many pools and spas report problems with phosphates. Things such as: body oils, cosmetics, suntan lotions, fertilizer, and even some stain and scale inhibitors can cause phosphate levels to skyrocket. Natural Chemistry has created the perfect phosphate removal products for whatever level you may encounter. It is important that algae be treated prior to testing and removal of phosphates. There are a few options of how to remove phosphates from the pool depending on the level registered. PHOSfree's no cloud technology works on the filter media to remove phosphates without clouding the water. Ensure that you begin any phosphate removal process with a clean filter. The second and third options are for high range phosphate removal. An older but still reliable technology is a flocculate called PhosFloc. PhosFloc will reduce high range phosphate levels to a more manageable range. It still may be necessary to use PHOSfree following a PhosFloc treatment. Another high range phosphate removal approach is to use PHOSfree Extra Strength. This product uses dual technologies to remove phosphates both in the pool water and on the filter. Unlike PhosFloc, PHOSfree Extra Strength can be vacuumed to filter and does not need to be vacuumed to waste.

PHOSfree Extra Strength

PHOSfree Extra Strength is specifically designed for high levels of phosphates and works on both the filter and in the pool for maximum phosphate removal. PHOSfree Extra Strength easily maintains low levels of phosphates in even the largest volumes of water.


PHOSfloc is a high grade, iron free floc that dissolves instantly in water. When used as directed, it reduces high phosphate levels in a pool to well under 1,000 parts per billion (ppb). Phosphates can then be reduced to near zero levels by using Natural Chernistry's PHOSfree or Pool Magic + PHOSfree


Reducing phosphate levels in pools is easy with Natural Chemistry's patented PHOSfree technology. PHOSfree is formulated from lanthanum (rare earth) compounds. When added to the skimmer, a thin coating of PHOSfree forms on the filter media. As pool water flows through the filter, phosphates are reduced to a very low level.

Pool Magic + PHOSfree

Use Pool Magic+ PHOSfree at both opening and closing to reduce the time and effort needed to open the pool. Works great with mesh covers!

Pool Perfect + PHOSfree

Regular pool maintenance is easy with Natural Chemistry's Pool Perfect+PHOSfree. The outstanding benefits of our SMARTZyme technology are combined with our patented industry leading phosphate removal technology. Pool Perfect+PHOSfree is added to the skimmer and does not cloud the water like other phosphate removal products. No other program compares to Natural Chemistry's Perfect Pool Program. Experience superior water quality with less work.
