so you had to drill the back of the tank? what size pipe did you use (goin down the back of the tank) what kind of pump? the size of the hose? how big is the wholes that you drilled ? and if i put 1 of them on each side of the tank i could have 1 gon into the skimmer side and the other 1 goin into the Refugium side


oh where did you get that black thing the water is runnin over than into the pipes
