Greetings RP! i will be building another tank and i want to share it here again...
so here we go...
...the system will be composed of two tanks. main tank is about 220 gallons (internal dimensions: 83"x24"x25.75") and the lower tank is about 160 gallons (60"x31"x20"). the sump will be more of an equipment chamber with a FBF (fluidized bed filter) system. overflow-sump-return system will also be integrated in this unit.
will start posting pics tomorrow. hope you'll enjoy this build...
