LONG:
I own the Neptune unit - aqua controller II.
The short version is: It's good.
However, the long story is:
Cost, Cost, and more Cost.
A word of caution: Know what you want to monitor, then see if the unit is right for you. Here is why:
1. The base unit is rather pricy. Ok, I can deal with that. Now, what do you want to monitor? pH, ORP, Temp? If so, you need the probes. Yes, there are kits available, and I'd recommend you start with one of those first. That is what I monitor - pH, ORP, and Temp.
2. If you want to be a complete nerd and connect it to your computer - you will need:
A. A Ground Isolator Cable
B. A Cable (or maybe make one yourself)
C. Software
3. X10 modules. Radio Shack sells them. Again, depending on what you monitor you may only need 1 or 10. I use one for my heater (safety measure), lights (vho, and MH), Fan (blows in canopy), and 2 power heads (wave maker).
As you may now be able to see, it is going to run you more than 300 bucks I'd wager. Not that that is a ton of money, but as you start putting it together, it adds up...Unit, 15 bucks for a cable, 10 bucks or so per X10 unit, 50 bucks ground isolator cable, 100 bucks software,
I've had mine now for over 8 months. I've had the PC board go out twice now. Both times I talked to Curt @ Neptune and he's provided good support. I had to ship the unit back (fed ex @ 26 bucks a shot) and they'd fix it in a day, then ship it back. Over all, good support. My only grip would be the 50 bucks I've spent in shipping for a unit less than 2 months old (at the time of failure)... (they could at least split the cost of the pc cable or isolator dealie).
Pros:
Does everything
Easy to use
Cons:
- Price
- Programming (I wanted to do something it couldn't)
I'll always own a controller now. They save me some time which I can spend elsewhere...
Hope this helps.
