    I'd suggest a huge sand or cartridge filter. Something in the 600 lb or 500 sqft range for that size pool.

    Very large filters have a lot of advantages. My pool is similar in size to yours (42K). I have a Triton TR140 that seems pretty well matched to my pool size.

    The only issue might be that a 1hp pump would not give you quite enough flow that you would need for a thorough backwash. My guess is it would do fine but a TR100 might be just a little better and save you some money.

    A large pool usually means dealing with a lot of debris so I would lean towards sand filters although there a probably thousands of pools your size that do just fine on DE or carts.
