How can we help you?

Start with your estimated pool capacity. Blue Original and Blue/White (with silver) are labelled for 7.5K–20K gallons; Black Original and Black/White (with silver) are labelled for 20K–30K gallons. Use the Product Configurator if you need help estimating volume.

Use the Pool Volume Calculator on the Product Configurator page. Enter measurements in feet and use your average water depth for a useful estimate. If you are unsure, a qualified pool professional can help confirm the volume.

Each KHF product title identifies a pool-gallon range. Choose the range that matches your pool as closely as possible and follow the product directions supplied with the unit.

Follow the installation directions supplied with your specific KHF unit. Keep water circulating as directed and ask a qualified pool professional if you need help with your equipment layout.

Maintain balanced water, make sure the filtration system is functioning, and follow the instructions on the product packaging. Begin with a clean filter when your routine calls for it.

Use the pump schedule and circulation guidance in the product directions. Good circulation is an important part of normal pool maintenance.

Pool systems and treatment plans vary. Review the KHF label and your equipment manufacturer’s instructions, and consult a pool professional before combining treatments or changing a system.

Only use products as directed. Check every product label and seek professional guidance if you are uncertain about compatibility, dosage, or the current condition of your water.

Clean, working filtration supports normal circulation and maintenance. Follow your filter manufacturer’s cleaning schedule and the directions supplied with your KHF unit.
