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. The minerals help keep low levels of chlorine more active and productive in the water. During the pool's filtration process, the minerals are rejuvenated each time they return through the cylinder. Granular minerals are lost through algae kill, backwashing, splash out, and filter cleaning. The harder the minerals work and the tougher the conditions, the shorter their lifespan. KHF works with a constant low level of chlorine. Residential: 0.5 to 1.0 ppm; Commercial: 1.0 to 5.0 ppm.\u003c\/p\u003e\n\u003ch4\u003eActive ingredients\u003c\/h4\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eCopper Sulphate Pentahydrate\u003c\/th\u003e\n\u003ctd\u003e86.85%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eZinc Sulfate Monohydrate\u003c\/th\u003e\n\u003ctd\u003e1.51%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSilver Nitrate\u003c\/th\u003e\n\u003ctd\u003e0.40%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOther Ingredients\u003c\/th\u003e\n\u003ctd\u003e11.24%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal\u003c\/th\u003e\n\u003ctd\u003e100%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eQuick Start Guide\u003c\/summary\u003e\u003cp\u003eMinerals dissolve into the water within 3 to 4 hours.

Clean or backwash the filter before adding KHF and ensure proper water flow from the skimmer and pump basket. Place the KHF unit in the pump basket or skimmer, ideally in the pump basket for increased water flow.\u003c\/p\u003e\n\u003cp\u003eAdd the unit when the pump has at least 3 to 4 hours left in its run cycle. This helps the minerals dissolve through the filter and pool. Run the pump during the heat of the day and circulate the pool's total water volume at least 1.5 times per day. This generally requires 6 to 8 hours of pump runtime, depending on pool volume and pump flow rate.\u003c\/p\u003e\n\u003cp\u003eFor best results, start each season with a new KHF pool unit.
