Or do the 2 just go hand in hand?

[Sir Patrick]

I test before and after every water change, and whenever anything is looking out of wack

[jimsflies]

SG is important because it is a measure of the concentration of salt in your tank water.

[whitetiger61]

has anyone besides me measured seawater

[MizTanks]

Now I feel like a dang fool~I'm always saying my sg is 1.025~this is wrong right.

[jimsflies]

No, that would be correct. your specific gravity is 1.025. Specific gravity does not have units. It is a ratio of pure water to (in this case) saltwater concentration.

[Sir Patrick]

the sea water off the coast of cali I tested was 1.015 or so. Its been a while, but where I measured it was much lower than my tanks water

[jimsflies]

According to info on the internet, natrual seawater in a reef varies from 1.025-1.027.

[whitetiger61]

i measured 5 miles off san fransico and got 1.037 on 5 different tests with a refractor

[whitetiger61]

this is why i decided to do a coral growth test @ 1.030
