Sump for 75g tank

[slm32123]

Well, I am looking at getting a 75gallon tank from a friend that is currently a FW aquarium. as far as i know it is not set up to have a sump. also i am not sure if it is glass or acrylic.

what would it need to be for me to be able to make a sump for it, i am thinking about using an old 20g FW tank i have to make the sump, but how would i go about setting it up, in the most discrete and simple way?

thanks in advance for any help

any sump you get/build will need 3 sections-one for skimmer,one for cheato+ one for return pump. i biult one out of glass tank w/aclrlic baffles. after a 18 month the silicone let loos and they started to move. my best advice would be find a uused acylic sump locally. it would be cheap considering the size you want.
