![]() 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

![]() I would ask a friend with a refractometer, recently calibrated to check your readings. Those hydrometers you are using are historically not very accurate.
Failing that, bring a sample of the water to another LFS and get them to check your reading. They will do this for free |

![]() I would trust a politiain before I would trust that swinging arm hydrometer. Just sayin'. :-).
In other words, definitely try retesting with a refractometer and see what you get. If the refract reads low then we'll talk :-) |

![]() If you can afford a new one I would go that route so you can be assured it is correct & get some calibration fluid as well. Talk to the crew at Concepts, Im sure they can fix you up.

![]() If you want a cheap RO/DI unit look at Aquasafe. They are in BC and you can order from them direct but they also sell on Ebay for cheaper. I got my unit with 5 sets of filters and a TDS meter for $100 but that was awhile ago. It doesn't take long to make your money back especially when you factor in your gas to go pick up RO water as well.
