For RKL to have the salinity option, you'll need the RKM-SL2 module, not the RKM-SL1 that's in that bundle. RKM-SL1 will give you ORP, and not salinity. DA has been struggling with their Cond./Salinity probe for the past year. I bought an SL2 and a salinity probe last year, and it has not worked. As of last week, DA is entering final production stages of their "fixed" probes. I'll be RMAing for one...
IMO, consider the Neptune Apex...

Even for these simple options you feel the Apex which is about 300 more is the way to go?
I am only really interested in the simple feature of duel ph probes the temp probe and I just recently heard of salinity probes and that sounded cool I don't need text messages or internet readings(although very cool).
Would you still recommend the 500 dollar controller vs this deal at 170?
