Best water tester for specific gravity/salinity is a 16" temp. corrected glass float hydrometer or a calibrated refractometer.I am starting to put corals into my tank. I was wondering what are the best water test kits for a saltwater reef tank?
I use:
Salifert for alk,calcium, magnesium ammonia and nitrates.
Pinpoint monitor for ph .
Pinpoint conductivity meter for specific gravity/salinity cross checked with a hannah digital refractometer.
Hanah colorimeter for phosphate.
Red Sea for iron, iodine and potassium.
Tom, which hanna meter do you use, the 713 PO4 or the 736 Phosphorus ?
