Salinity and cheap hydrometers
We all have a hydrometer right? Two even...? I thought my readings between my two probably set my salinity at around 1.025-026. Boy was I wrong! Try a refractometer people... I took a reading... almost 1.028! I know salinity is relevant, and what we should be looking for are keeping large swings at a minimum, but remember, salinity affects the levels of concentrated salts and minerals in your water, and long term ranges out of the norm of NSW are bound to adversely affect our corals.
Japarto at Safari has a nice unit ... amazingly accurate, and simple to use and calibrate. If we all had two, we've spent $30 - $50 already, and can't be sure of our readings... I would recommend bucking up and having peace of mind.
