What is your opinion on tanks with hang on back filters to help save money to buy more coral instead of purchasing a tank a sump and not being able to buy as much coral in the long run?

Guys, Merry Christmas and Happy New Year to all...as one of our new year traditional activities..we always clean the house in and out and get rid of all old and unused items and our 125 gal tank has been given passage year after year after year and this is the last year. We bought it 10 yrs ago...
