I am having some ph stability issues. got it remedied for the most part by opening up the windows. but looking to buy a CO2 scrubber from BRS and wanting to automate the scrubber to run when the ph drops to 8.2 and shuts off when it hits 8.3. has anyone done this before and if so is there a write up or article on how to do this? I want it to work with my apex also.
