Salinity

[Reef.]

Lol. I’m feeling much more comfortable having this thing now. At least for my newly mixed water it’s easy to get water to the right temp and use it. I’ve got a graduated cylinder for tank water but it’s warmer. I know there are charts out there though to convert. But once I see what it should be I’ll be able to keep it consistent.

I just sit 500ml of freshly mixed salt water in a bowl of hot water, bring that to temp to check the salinity.

Here is a salinity correction calculator but I prefer to bring to the correct temp of 77 and check that way.

Thanks for that bookmark. Very helpful. And I was just thinking I just need to wait for my tank water to cool down a degree to get to 77 before I check the reading. I’ll figure it out. Won’t be too hard. Il still just in shock it has been so far off.

Hi,
Some article from Randy Holmes for hydrometer measurement with table for temperature compensation: http://www.reefkeeping.com/issues/2004-07/rhf/
