Boy I feel like a dumb ass now, I knew that but it took you to say it for it to click in my run down, dog tired gray matter. Thanks again Kien.

Well, unlike you I DID NOT know that until I actually tried to buy one myself

One of the few thing I remembered from school, that and how to sneak out of the school and not get caught to go well let's just say......................get happy.

Ok so I think I have it figured with some inlightenment from Kien. Here is what I might look into.

Neptune Systems Apex Lite Controller Package:

-Package includes: Apex Lite Base Unit, Apex Display Module, Temperature Probe, and Energy Bar 8 Module.

And add on:
- Conductivity Probe
- pH Probe - Lab Grade
- ORP Probe - Lab Grade

Any other suggestion for add-ons

did you figure out what the orp probe is yet?

Not 100% but I think it could stand for Oxidation Reduction Potential.

The standard package and unit won't allow you to measure salinity. To monitor salinity, you need to buy the probe ($130 ) and the PM2 module ($92)

Also The Apex base unit supports 3 probes. (Temp, pH, and pH/ORP). The Apex. Lite only supports 2 (Temp, pH)

Make the orp probe the last you add. There is much debate about what orp can really tell you. It certainly is not as easy as "orp should be X". When it drops, it suggests that something has changed, but you don't know what.
You can manipulate/control orp with ozone, bit even that can be tricky because the orp readings can be normally erratic.

I don't think that I am going to add a ORP probe because I have not been able to find enough info to tell me that I need to have this in my tank the way it is set-up.
