The lowest hysteresis setting is .1 at this time. I will ask Eric if it is possible to get a lower resolution for it. basically if you set the target to 8.0 it will trip at 7.9 and 8.1. It could be either on or off depending on how you program it. You do not have to use hysteresis but keeps the output from cycling on and off quickly.
It is probably from an Apex user. Most controllers will control a Solenoid.
Ouch.
I am curious either way though, why did you eliminate the Apex?
I think he meant nothing less than an Apex Classic, not an Apex Jr. But I agree, most if not all controllers will control a solenoid.
I am an avid Apex user, and have been for many years. I have no stake in Apex, but I stand by their products and customer service.
If you went with the Apex Classic, you'd be up and running in a matter of minutes with this. It controls pH down to 8.22, no problem. On BRS for $550. Same as Archo
If you went with the Apex Jr., you would need the VDM module and pH probe, so on BRS, you're looking at $365 for everything. And, you'd still be up and running in a matter of minutes, controlling your pH down to 8.22. Literally minutes.
Or, you can go big and get the 2016 Apex, for 800 bucks, and be ready to go when the Triton comes out next year, but I assume that's outside the price target. (It's outside mine, hah)
If you're new to controllers, they have entry level guided setups for everything, it's best in class stuff. I just helped with an Apex install for a local reef buddy, using only the "Tasks", and it really is simple to use and operate. Plus there's a literal army of folks who are willing to help should issues arise.
And, for what it's worth, if I was going to be purchasing anything this expensive, it's going to come from a big box store or
Amazon with a very clear and robust return / exchange policy. I clicked around on a couple of the distributors and am taken to godaddy sites and broken links. Sketchy at best.
