PR-10,000 is a highly concentrated rare-earth phosphate remover. It is formulated to react with phosphates in the water, allowing them to be removed from solution. It reacts with all known types of phosphates on contact and hardens them into a fine precipitate, which falls out of solution. The inert phosphates then floc out, to be vacuumed or filtered out of the pool. PR-10,000 causes cloudiness, which can last anywhere from a few hours to a few days. Use as needed, and do not exceed the recommended dosage unless otherwise specified (see below).
Because of PR-10,000's concentration, a little goes a long way. A dose of PR-10,000 may be surprisingly small to you, but watch it work. PR-10,000 is one of the original Orenda Products and is professional grade.
Why Remove Phosphates?
Unlike most other contaminants in water, chlorine cannot remove phosphates, because they do not interact with each other directly...so to reduce phosphate levels, you will need a phosphate remover.

How to use PR-10,000
We recommend not exceeding 8 fl.oz./10,000 gallons for a normal treatment unless otherwise specified. This is recommended because of the impact on filter pressure. When phosphates are removed, there is a fine precipitate that falls out of solution. Too much precipitate at one time can cause high pressure in filters.
PRO TIP: Try using PR-10,000 in a commercial spray bottle, and broadcast it across the surface of the pool. The cloudiness is less severe, and you still remove the same amount of phosphates each treatment. Consider following it up with CE-Clarifier, also used in a spray bottle, to help filter out precipitate faster.
PRO TIP 2: If your pool is cloudy/dirty enough that you cannot see the main drain at the bottom of the pool, do not use PR-10,ooo without also purging with CV-600 or CV-700 enzymes. It may not be enough to clear the pool. If there are enough oils and organics in the water, those oils will float and can stick to the falling PR-10,000 fallout dust. This means the dust can stay suspended in the water for days instead of clearing overnight. Enzymes accelerate the clearing of a problem pool.
For green pools, follow our Green Pool Cleanup procedure.

Phosphate and How They Impact Chlorine
PR-10,000 (https://orendatech.com/orenda-products/pr-10000/) and phosphate removal
Why remove phosphates (http://blog.orendatech.com/phosphates-algae-chlorine-demand)? Because phosphates are essential micronutrients that allow microorganisms like algae to reproduce well. Removing phosphates won't kill algae, but it can slow their reproductive rate, allowing chlorine to stay ahead of it.
Sanitization is all about the killing rate of the sanitizer versus the growth/reproduction rate of the microorganism. Phosphate removal can significantly slow down the growth rate (http://blog.orendatech.com/phosphate-removal-pillar-3), and supplementing chlorine with enzymes (http://blog.orendatech.com/organic-waste-and-carbon-management-pillar-2) can optimize chlorine efficiency and killing rate.
Where Do Phosphates Come From?
Phosphates get into swimming pools in three main ways

Have you ever wondered how and why phosphates get into swimming pools? We know it's important to eliminate phosphates, but why are they there in the first place? There are many different types of phosphates, and there are three main ways they can get in your pool.
Phosphate Removal is Orenda's Third Pillar of Proactive Pool Care.
1. Chemically - Most pool metal and scale control products (sequestering agents) are phosphonic acid-based. Don't worry, not our SC-1000! When new or resurfaced pools are started up, the common practice is to put these sequestering products in the water on the first day. If they're phosphonic-acid-based, you're basically pouring in liquid phosphates.
2. Organically - Phosphorus is a naturally occurring element. It's in soil, so naturally, it can find its way into swimming pools. Think of a rainstorm...for swimming pools with bushes or landscaping near the pool, phosphates can get washed into the pool that way. Another factor is for pools with well water...phosphorus seeps into groundwater through the soil. Fun fact, so can metals. Furthermore, phosphates are key ingredients in most fertilizer products.
3. Finally, your tap water. We already discussed well water often having phosphates in it, but municipal water sources often have phosphates too. Why? For the same reasons listed in item #1. Water has to travel long distances in pipes, and those pipes are vulnerable to corrosion--and the opposite consequence--scale. Phosphonic acid inhibits both of those problems and protects pipes. Sequestering products like phosphonic acid also address water fouling in water treatment facilities, so nowadays it's very common to find phosphates in your fill water. That's one of the many reasons we urge you to test your fill water!
