Do You Need Chlorine to Control Algae?

Contrary to what many people believe, chlorine is designed primarily for killing off bacteria and other contaminates. It is not formulated specifically to control the growth of algae. By using chlorine alone to prevent algae growth, a great deal more “shock” will be required. “Shocking” your swimming pool with a large dose of chlorine is an effective way to kill existing algae and bring your pool back to its clean, clear glory. This will generally take between one and three days. However, if your swimming pool’s condition is particularly dirty, it can take up to a week.

Because the country is still in the midst of a chlorine shortage, attempting to use chlorine to control algae isn’t your best choice of method. At 1 Stop Pool, we often suggest using preventative maintenance practices like keeping the filter clean and using preventative algaecides such as Easycare Pooltec, Algatec, and the Pool RX, along with phosphate removers like PR10000. Using these products along with  the ProTeam Supreme Plus we discussed in last month’s blog can greatly reduce your chlorine needs this summer!

Pooltec and Algatec

Easy Care’s Pooltec is 3-in-1 multitasking product that kills and prevents all types of algae growth. Pooltecs environmentally safe polymers works with all types of sanitizes to provide superior water quality, clarity, and improve water sanitation. It produces ultra-clear water and is a very effective chlorine booster for both chlorine and salt pools. Pooltec helps increase chlorine residuals in salt pools especially during heavy usage periods. Pooltec® also keeps pool water consistently treated, eliminating the need for cleanup products such as algaecides and clarifiers.

Easy Care’s Algatec is a powerful, synergistic algaecide, water clarifier and chlorine booster for swimming pools. The product is metal-free, non-hazardous to handle, and does not remove chlorine from pool water. It is effective with or without chlorine, helping improve the quality of the water and increasing swimmer comfort in pools, spas, and hot tubs. As an algaecide, Algatec kills green and yellow algae in four hours to one day and eradicates black algae (fungus) in seven to ten days. Algatec’s clarifiers flocculant result in very clear water in your swimming pool by boosting chlorine and bromine effectiveness up to 600% while reducing sanitizer usage between 25% to 65%. Algatec has the additional benefit of being compatible with all salt cell systems and also helps improve salt cell performance. It will not interfere with pool water pH, chemistries, or sanitizer levels, and you can swim immediately after using it to treat your pool. By using Easy Care Algatec as a preventative algaecide, you kill off algae trying to grow in your pool.

PR-10,000

Adding PR-10,000, a highly concentrated rare-earth phosphate remover, takes away what algae “eats.” Combined with ProTeam Supreme Plus, which removes what algae “breathes,” produces a multi-level defense against algae. PR-10,000 reacts with all known types of phosphates on contact and hardens them into a fine precipitate. These fall out of solution and floc out before being vacuumed or filtered out of the pool. (Please note that PR-10,000 does cloudiness in the swimming pool’s water. This cloudiness can last from a few hours to a few days.) PR-10,000 is one of the original Orenda products. It is a concentrated, professional grade product.

PoolRx

PoolRx kills existing algae quickly and prevents future algae growth. The product’s chelated minerals boost low levels of chlorine to be more productive in the water, resulting in greatly increased clarity. The minerals dissolve and form a stable residual throughout the pool. As the minerals pass over the PoolRx unit during circulation, they are revitalized and last longer. For very large pools, pools in poor condition, or green pools, adding PoolRx booster minerals will eliminate and prevent algae and reduce chlorine demand for up to six months.

ProTeam Supreme Plus

As discussed in last month’s post, ProTeam Supreme Plus helps reduce your chlorine needs while ensuring you can maintain your pool properly. It is a once-per-season treatment that reduces eye and skin irritation, controls algae, and improves filtration. ProTeam Supreme Plus enables your pool’s sanitizing agents to work efficiently by keeping the pH of your swimming pool in the proper range.
