oversize cartridge filter

[papadoppa]

My plumber said he can get me a CCP 520 for 1000- which is less than I can buy a 420 for. My pool will be small--15x25x5 IG but am I to understand that the larger the cartridge the less often I have to maintain it? Is there a downside to this?

Thank you

Nope. Get the 520.
