Dome's are usually for rockwool,we dont use one on the aero-rooter.I dont mix any rooting stuff in my water,I use a gel,you dip clone once and then place in rooter. I run the nute's at 600 ppm.If your getting good action from your sprayer's then you dont need an air stone,the water splashing will aerate it just fine.
