My liquidator works ok, but I am not enamored with the quality of it. I too am trying to put together a dosing system. I have a BubbleMagus BM-T01 pump with three heads which hopefully will do the trick. With the help of another guy in Houston, I was able to get 25 gallons of really good quality 12.5% bleach in a plastic, safe for bleach container. The biggest problem is the gassing off of the bleach. If I seal the tank it expands, if I let it open ever so slightly, I assume I am losing strength, no?
