You guys are right . . . again.

So, I broke down and bought a refractometer. Been using 2 hydrometers (figured at least one would be accurate). Found my sg to be 1.28 instead of 1.25.
I guess an RO unit is next - per you guys advice.
There should be warning labels on saltwater aquariums advising you that once you start in the hobby, you will not be able afford to send your kids to collage.

1.028 isnt that bad really, it is high but my tank stays at 1.027 at all times so I can keep my nutrient and elements as high as possible, but its nice to have a buffer zone 1.025 is best is you have lots of evaporation and your salinity fluctuates alot.

I couldn't believe how far off my salinity was too when I first got a refractometer.

i think mine first measured in at 33 when the hydro said 1.023.
if you go and buy a ro/di, just go all out. i had a cheaper one and couldn't get filters. typhoon filters seem to be easy to find and a standard size. it's an expensive initial expense, but cheaper to maintain.
imo of course
