Thank you everyone for your information. I was thinking of adding the salinity probe because I have never owned a refractometer only a swing arm hydrometer. I figure monitoring salinity isn't something I regularly do, so having it always available would be really nice. I would like an apex but I'm looking at at least $150 more for the ph probe package, then whatever it would cost to add on the salinity probe (like another $125) . I agree that good equipment is better than a controller, but I only run a heater and lights along with a retun pump and RW-4 nothing could really go wrong other than the heater failing. I am looking at this more for monitoring than control. And this would offer the little bit of redundancy I need and connect my data to the web (rather than buying multiple pinpoint individual monitors). Those are my thoughts currently although I'm going to need to pull the trigger by the end of the weekend if this is actually going to happen. I'm just fighting myself, playing devils advocate saying "do I really need this? At what point is it all TOO much?"
Thanks

For salinity a digital refractometer is great, I have had floating hygrometer, swing arm, hand held refratometer and pinpoint monitor but I will take my Milwaukee digital over all the others. Good testing kits are more important than a controller as you have to still have a way to verify and double check and calibrate the reading from any controller.
