The wifi on the machine, that is needed to view, monitor and change setting is pretty finnicky with my experience. The instruction/troubleshooting manual is of little to no help. In fact the manual is more like a padded review of how great and easy it works, not what to do when it doesn't (which seemed to happen often). Multiple dosing issues regarding Ph has left me not trusting the machine. The manufacturer and its minions (atlantis) sure do talk it up, but the performance capabilities have yet to be realized due to errors, connectivity issue and dosing discrepancies. Look elsewhere for an automated system, this one is troublesome.
