I have some kamoer dosing pumps for sale. 1 basically new BNIB Kamoer FX-STP2 wifi dosing pump. I turned it on and ran some RO through it to test it out for a short amount of time. Works perfectly, calibrated perfectly and is quiet. Comes with everything in original box, Instructions, tubing...

Unopened, bought a week back. $60 shipped.

Why is it a new Apex ph probe has to be in a system for some time, like four weeks, before it will calibrate and give an accurate reading? Working my 2nd Apex install, and getting the same low ph reading that I did on my first, it only calibrated and read accurate when it was in the system for...

Just need to add a 2nd Temp probe and my salinity probe to my PM2 module and then I will be done. Then I just have to mount all of my controllers and this job will be completed. Here is where I keep my parameters at all times: Water Parameters: Alk: 8.0 dHK CAL: 420 MAG:1300 Salinity: 1.024...

It's up and running, calibrated my PH Probe next will be hooking up my PM2 Module so I can connect my salinity probe. Then install my ALD module / Leak Detector & probes around my sump area. Also, my Amazon Fire tablet has been linked to my Apex and installed it on the front of my Apex...
