Hi Bio,
Yes, those atomizers..........need 30 psi working pressure as per instructions but, they do work real good at 20 psi. And, even the one from HK is starting to work better, not perfect but, better. I am getting more of a fine mist than bubbles from all of them. If the DPs are a good indication then I am doing OK. I am getting yellowish green in about 6 hrs. Lol, I am still going to have my 2 Victors fixed, so I can get more pressure if, I so choose.
