Thanks, will do. I added a cup of salt in the sterilite and put an air pump in then tried the refractometer after about half an hour just to see. Either my eyes are getting old or those lines are waaaay too small haha. I'm getting a reading of either 1.002 or 1.003....hard to tell. All I'm sure is it's less than 1.005 (for now...not sure if that changes after 24h). I guess that'll be even lower once I add it to the tank since it's only about 50%. But it's probably better if I raise it slowly to not crash my cycle. Will update you guys in a few weeks or so once they're fully acclimated to brackish. Thanks again
