The Blackstone BL7 Dosing pump allows complete control when dosing as the pump is fully adjustable from 0 to 100%. and each stroke can be seen with an LED on the pump next to the control dial.  This can be wired into the Thermo scientific alpha 560 PH controller and the industrial PH probe to allow you to dose a metered amount of bicarb into a pond system where people are struggling to control their PH and KH in a soft water area. This will then save maunually adding bicarb to a pond to maintain the PH and KH. It can also be used in conjunction with RO systems to control PH and KH and also be set up to stop a PH crash.
