So, official ordering of *A* controller, just not the one listed above.
So Profilux officially lost my business for a number of reasons. In quadruple checking my modules, I noticed that the vortech module ONLY works on the 3. So we looked at the three. It appeared to even contain the modules needed to work the salinity probe! How Awesome!
So I go to order this (now more expensive) controller. In two attempts, their system would not take my order. How odd. I go to their forums (which are mostly in german) to look for a clue. It is there I discover that in order to measure salinity I would need a 3EX, the three does NOT have the module built in. Upon further reading I discovered the picture and description on their site of the 3, is really the 3EX.
I'm terribly thankful their system failed horribly. There's no real description of what is needed for anything on top of being a much more expensive system. If I cannot even figure out what I need and your support sends me to an aquarium forum, I am frustrated.
I decided to go with a system that I was confident would do what I asked it to. It won't do anywhere near as much, but it will do it cheaply. I went with the Reef Keeper Elite. It will still email me, it still has an iphone app and I can eventually measure salinity. Not to mention a quarter of the price. Now I will use the AI controller I already had and the vortech controller I already had. The cabling won't be as pretty, but Digital Aquatics can at least tell me what their software can do.
It will be here next week.
