Website shows Hayward C5520/C5525 Generic Cartridge (PA137) - PL0115 is best match/replacement for my existing Blue Haven Pools Cartridge. However, my current cartridge reads "138" vs. PA137. All other sizes (length/diameter) line up. Is this the right cartridge for my 450 & 550 Series Smartfilter system? Model No. C5520BHMB
