For best results, especially in high flow/high sediment applications, we suggest you team up a GAC post-filter with a Fibredyne pre-filter (Pentair Pentek FloPlus-20BB, EP-20BB, or C1-20BB). Extruded Carbon Block is another great pre-filter choice (Pentair Pentek RFC-20BB or NCP-20BB filter).
• LONG FILTER LIFE OF 6 MONTHS – 25,000-gallon capacity translates to replacing the filter every 6 months (or when you notice a drop in water pressure/quality). You can also stress less and live more when you purchase a convenient case pack! Your future self will thank you.
