leave it 2 cups isnt going to matter Catherine, i do it all the time if im under in salt i just add a couple more cups or over i leave it out.

Good plan. I'll just let it go and see what happens. Its still mixing up now, so now I'm just waiting to see.

ya in your tank 180 gal 1-2 cups isnt going to matter, i would do it all the time then you are going to be low and have to drip concentrated salt water to bring it up.

Those extra two cups definitely did something...

When we mix up our water we do so using 30g of RO/DI and 25 cups of salt. This time though 23 cups of salt yielded 1.042 SG. We're both confused how this happened, but I'm thankful that I re-test everything before we use the water.

New MHs are ordered and we're just waiting on delivery. I'm sticking with my favorites, 250w XM 15K moguls.

that dont make sense when I make salt water and i do a 5 gal change i will check my salt in the main display. If the Salt content is high i will take out of cup only making it 1.5 cups of salt. when its lower i will add a extra cup to the 5 gal change.

Did your refractometer accicently get bumped? Maybe recalibrate? Just a thought.

The display is fine, its the make-up water that has the problem. Calibration shows the refractometer is fine. We're just chalking it up to a one-off experience. We just ended up cutting in RO/DI to bring the salinity down.
