neptune salinity monitor

[jamal]

is anyone using this add on to the apex system to monitor salinity if so, what are your thoughts on its accuracy. I'm think of getting it.

I have it on my tank. It works well. Use the refractometer and use the baseline as your number. So 1.025 is 34.5 as it reads. You also need to add another temp probe in order for it to be accurate. It fluctuates the reading up as temp rises during the day and the down as it cools. If you get the second temp probe that hooks into this module it eliminates it as it takes that into consideration.
