Best way 2mx3m pool metal frame (Arleston DE24)

Ex condition less than 24months old - reason for gifting is we’re getting a bigger pool as kids are bigger - and want something deeper. Very sturdy takes about 6/8 hours to fill - will obviously want cleaning as it’s been rolled up since last summer - collection only - u could get a new filter pump online Amazon very cheaply we just used chlorine tablets and changed water regularly
