Just filled with media and neo mag. Also comes with a 20lb Co2 tank and regulator. Tank probably has 4 to 5 months left of co2 on a 250 gallon sps dominant system. I ran this on my 270 gallon DT and frag system and it kept up without issue running barely over 1 drop per second. Can sell ready to hook to an apex or stand alone with a Millwaukee 122 ph controller.
Rx, co2 tank and regulator $250
