im setting up my sump and going to put in baffles so i need to know how high to make the baffle for the skimmer section i have a asm g2 skimmer...i have read it should sit in the water anywhere from 6 to 9 inches...i dont want to make the baffle too short cuz once the tank is up and running it will be impossible to change the baffle hight without ripping down the tank...thanks for the help
