Q: Will this tank fit my existing Cristal-Flo II filter? A: Yes — if your system originally uses a 22″ diameter tank, then SKU 145366 is the correct replacement. Double-check model diameter before purchasing.
Q: Do I need to replace the sand when installing this tank? A: Not necessarily, but if the media appears worn, compacted, or the laterals show damage, it’s wise to replace sand and inspect internal components for optimal performance.
