This is probably the final piece to my Neptune Apex controller. I now know the critical readings to my 60 gallon reef/fish tank at a glance. This gives me the freedom to enjoy my tanks inhabitants.
In my book Neptune apex is the only way to go in tank controllers and the PM - 2 conductivity module closes the door with peace of mind.
Make sure to purchase the additional heat probe and calibration fluid with your PM-2 module. The setup is supper easy.

I haven't gotten my complete apex system up and running yet but am very excited to do so.

waited a month or so to post this review as the probe seems to have a break in period. I was getting swings from 31-35 ppt. It is now stable and being used to trigger salt additions when enough salt creep occurs or time. Working excellent now, this is something that has been much needed in the industry for some time. I have used it to calibrate my handheld meters which were really close anyway and would recommend to all apex owners@!
