Napalm is ~120ml, so depends on how much clen you'd like. Dsade recommended only 25% additional solution for Evis, so I'm assuming it's about the same for Napalm since it's the same base. If that's the case, the most you'd want to add is 30ml (after you've used 30ml, or ~10 applications of 3 pumps). If you have 200mcg/ml concentration, you'd end up with 6000mcg, which would put you at 50mcg per ml. It's about 1ml per pump, so you'd be getting 150mcg per 3 pumps. Sounds good to me, but 300mcg per day may be a bit high though if you dose twice...
