Planning to do a central filter system.

[mfkjph]

I was planning to do a central filter sysem instead of a individual filter system on each tank Im planning to open a store so I needed to know how to do a central filter system
Each rack will contain 5 tanks ( 48x24x15) and there will be 5 racks
Maybe someone can teach me how to do a central filter system and how to plumb one

Thanks.
