KHF Pool Unit

KHF contains a proprietary blend of minerals that continuously and effectively eliminate algae. The specially treated alloy cylinder is packed with KHF granular formulation. These minerals dissolve from the cylinder and form a stable residual throughout the pool water for up to 6 months. The minerals eliminate algae while helping low levels of chlorine stay more active and productive in the water. During the pool's filtration process, the minerals are rejuvenated every time they return and pass through the cylinder. KHF works with a constant low level of chlorine.

Also ideal for salt pools

KHF improves the saltwater experience. The minerals reduce salt chlorine production needed to help keep a salt pool algae free. Less salt chlorine production can extend the life of the salt cell and reduce the amount of acid needed to balance pH. KHF helps prolong equipment life while supporting water quality.

Directions for use

Use this product only in a manner consistent with its labeling.

• Clean or backwash your filter before adding KHF and remove all debris from the skimmer and pump basket.
• Place the KHF pool unit into the pump basket or skimmer. Ideally, place it in the pump basket for increased water flow.
• Add the KHF pool unit when the pump has at least 3 to 4 hours left on its run cycle so granular minerals can dissolve through the filter into the pool.
• Run the pump during the heat of the day.
• Turn over the total pool volume of water at least 1.5 times per day. This generally requires 6 to 8 hours of pump runtime depending on pool gallons and pump flow rate.
• Do not re-clean or backwash the filter for at least 2 weeks after installation so minerals can dissolve through cartridge, DE, or sand filters.

Maintain normal pool chemistry ranges

• Replace the KHF unit in the basket every 12 months.
• If algae returns or the water looks dull, add KHF booster minerals.
• Add a KHF booster after 4 to 6 months if needed.
• No phosphate removers, algaecides, or clarifiers are needed.
• KHF is not compatible for use with bromine or biguanides.
• Do not add Cal-Hypo products directly to the pool. Cal-Hypo products must be diluted before adding to the pool.
