Pool Clarifiers – What are They?
The most common type of pool clarifier chemical sold and used is known as a PolyDADMAC, an ammonium chloride with a highly positive charge density. Different concentrations of 10% to 40% are useful for nearly any negatively charged colloidal particles.
Another common and very effective type of pool clarifier makes use of the natural cations known as Chitosan, or Chitin. Extracted from crab shells, chitosan is bottled in low concentrations of around 10% and are usually labeled as a Natural clarifier.
Another natural chemical used as a pool clarifier are Enzymes, positively charged particles that actually do consume organic and inorganic colloids, or suspended material. Especially useful for oils and organics.
A group of clarifying agents known as Polyacrylamides, or PAM, makes another fine ionic polymer. For pools, you’ll find these packaged in the form of a Gel or Cube. Long lasting and easy to use, but the gel can clog the fine pores of DE or cartridge filters.
And there are Aluminum Sulfate products, called simply Alum by those in the know. Alum is used as a flocculant, as it can clog pool filters. After adding a Pool Floc product the filter is shut off, to allow the heavy particles to sink to the pool floor, usually overnight. A slow vacuuming to waste the following day will expel the gel-like material, which has the consistency of wet toilet paper.
Finally, we have Blended Clarifiers; formulations that contain mixtures of polymer ions, chitosan, enzymes, phosphate removers or sulphates of alum. Multipurpose blends solve several problems at once. These will usually have higher prices, as they contain several pricey ingredients.
