Stella Posted March 27, 2011 Report Share Posted March 27, 2011 What do you guys use to measure your salinity? no, I haven't yet caved in to the temptation to do native marine I have a number of fish in quarantine at the moment and am aiming for 7ppt salt as a whitespot preventative, so fairly low compared to seawater.

puttputt Posted March 27, 2011 Report Share Posted March 27, 2011 The only accurate way is to use a refractometer, one that adjusts automatically for temp variations. They aren't too expensive - $80 - $100, something like that and they last forever. Quote Link to comment Share on other sites More sharing options...
suphew Posted March 28, 2011 Report Share Posted March 28, 2011 You can also get electronic salinity probes which are as accurate if not more so than a refractometer You could also get a hydrometer, not as accurate as a refractometer but should only cost you $10 or and if you go to a knowledgeable store they will be able calibrate it against their refractometer which should be good enough for what you need to do.

Stella Posted March 28, 2011 Author Report Share Posted March 28, 2011 hmm, maybe a plan to get a cheap hydrometer and see how much use I get out of it. So would a hygrometer read the low SGs well? Does temperature matter? Thanks Quote Link to comment Share on other sites More sharing options...
spoon Posted March 28, 2011 Report Share Posted March 28, 2011 the temperature will effect the SG reading and hydrometers are cheap but can be wildly inacurate i would see if you can borrow a refractometer no point buying one if ur not going to use it all the time Quote Link to comment Share on other sites More sharing options...
