Premixed water from big als warning**
Just curious as to how many people purchase pre mixed saltwater from bigs? Of those of u who do, how many of u test the specific gravity of it before putting it into your tank? I just picked up5 gallons yesterday and was going to do a water change tonight but after testing it this was the result. I under stand these hydrometers aren't that accurate but I feel this is way to low. You think they would test there batch better before selling it to customers
