Cartridge Replacement for 90 sq ft. Pool Store Brand

[Guest]

So I think I made a mistake in buying the generic pool store brand pump/filter.

It's a "Black Diamond" cartridge filter. 90 sq ft. I need a replacement cartridge now.

Can I buy any 90 sq ft. cartridge, or will I have to buy the pool store brand (which is $80+)?

If you can match the ID, OD & Height of the original you can replace it. The square footage might be an exact match but it'll most likely be close.
