I dip a straw into the bottle and get about an inch worth in the straw, holding my finger over the other end I transfer it to my loop. I do this with pump circulating and UV lights on. When you add it, you can see it kinda pulse thru the system and the glow get brighter. I do this a few times until its doesn't make it glow brighter. Its possible that I'm using too much and it effects the cooling properties, but I don't know. I havent done any testing of this.
peace.
