those handler 3 chemical inductors look really nice but very expensive, but this is what i was thinking.  Could i put all bulk chemicals overhead and run a hose to the handler.  The handler has gallon marks on it so i wanted to gravity flow the chemicals into the handler, using that to measureit s i dont need all the expensive bulk chemical meters.  then i could just open the handler and suck it on and  into my nurse tank.  Would this work well?  How long would it take the handler to suck in say 30 gallons of lexar? Can i just dump dry atrex and princep into the handler and suck it on?  Is there a cheaper option?
