Pool Algicide for Clean Swimming

A good pool algicide is essential for backyard and community center swimming pools. In fact, it helps to prevent and treat algae infestations in both swimming pools and hot tubs. At Lowe’s, we carry a broad selection of algicides to treat common pool algae, including green, pink, mustard and brown varieties. It’s best to use algicide as a follow-up to a shock treatment to return your pool water to crystal clarity.

Staying on top of swimming pool algae is an important part of pool maintenance. Algicide can be stored with your everyday pool supplies. Without prompt and effective treatment, algae will only multiply and grow. A strong and fast-acting algae killer for pools is ideal for clearing your water and can help to prevent algae from returning. Some formulas contain built-in clarifiers, and you can even use them with saltwater pools and saltwater generators.

After you’ve picked out your algicide, be sure to check out our guide — How to Open a Swimming Pool — for great tips on prepping your pool for use as the weather warms up. Learn how to properly remove a pool cover, reassemble the filter system, and more.

Frequently Asked Questions

Q: When should I use algicide in my pool?

A: Pools need algicide about once a week, following a shock treatment with chlorine, to treat an infestation. If you do this regularly and with careful attention to proportions, it should prevent the algae from returning.

Q: Do I use shock or algicide first?

A: When treating an infestation of algae, it’s best to first use shock in your pool water. Shock is a chemical formula, often containing chlorine, that you can add to swimming pools to raise the level of chlorine in order to kill algae. Once chlorine dissipates to its normal level, then apply a quality algicide.

Q: What kills algae in a pool fast?

A: Applying shock to your pool superchlorinates it, effectively killing algae. Add your algicide once the chlorine level returns to normal and allow the algicide to dissipate for 24 hours. After that, your pool should be ready to use.
