What probes do you use and..

[my5girls]

where do I get them. I am setting up a 125 reef and have a place for 4 probes in my sump. PH, and temp..anything else I need?? And I have looked at a few sites and can't seem to find any probes. Maybe I am just overlooking them? Also, I used to use a plastic thing, can't recall the name right now, to measure salinity...I know I have read about something new that is more accurate..What is it called and where can I get one of those also. thanks so much!!

hey
dont know anything about the probes. but the plastic thing is called a hydrometer and the more accurate item is a refractometer
do a search on google, also on the big auction site in the sky they have them available.
