i had a cal ph salinity and temp monitors on my 90. they arent worth the money. you have to calibrate them all the time and i still used test kits to correlate them. once you get ur tanks consumption of cal down you wont need that anyway. if you really want one i would get the ph one then you can tell alot about whats going on with you cal and alk with that
