Question,
I'm using my refractometer http://www.google.com/url?sa=t&sour...gX-lJ39s0yKdBlR6w&sig2=qGB1soPRqG8NtsQFuD1iPg from my SW reef tank to measure the Salinity in my Pool. I also checked the calibration of the Refractometer this morning.
What's weird, is I'm getting a 5PPT (5000ppm) reading - considering I only added (for the first time) about 2PPT last weekend - and then just finished draining 1/2 the pool cause my CYA was still well over 100 - for the life of me, where is this salt reading coming from? This is weird, because a refractometer is supposed to be "spot-on".
Other than "best guess" (I put XXX lbs of salt in YYY pool) - what other methods are people using to measure Salt?
