What is your salanity?

[rwm555]

My LFS says I should run 1.021?

What does everyone else run?

 

[46FiatYamaha]

1.026 for me

 

[jener8tionx]

I think many of the LFS use lower salinity to save $$$ on salt. Natural sea water it 1.026 according to the experts around here. That's why I aim for that value.

 

[lombard0]

I keep mine at 1.025 to 1.026.

 

[SidCat]

I also try for 1.025 to 1.026.

this is a poll on specific gravity- NOT salinity.

FWIW I run salinity at 35ppt

 

[lucas73]

35ppt or 1.0264

 

[ChrisKirkland]

35ppt (or 1.0265)

 

[Korrine]

It depends on what you want to keep in the tank. Fish can be kept a lower sg while corals really need the natural level.

Keep mine from 1.024-1.025

1.025 here.

 

[vetdog]

I keep my salinity at 1.024-1.025

everytime i tested the seawater around here its at least 1.035 and peaks higher than 1.055

1.024 to 1.026

the poll values are not in specific gravity and the original question asks what your salinity is?

 

[mmedeiros2]

Mine is at 1.021. The reason the lfs keeps theirs low in the fish only tanks is to fight off parasites. It also costs less.
I do not have corals and 1/2 even cup of IO salt / gal. = 1.021.
Easy for me.

the poll values I see above are for S.G., capn.

Natural ocean water has an average salinity of about 35 ppt, corresponding to a specific gravity of about 1.0264 and a conductivity of 53 mS/cm.

1.025 which is lower than NSW but I have nano tanks. Experience has shown that lower salinity (IME) is tolerated better than high salinity so I want a little extra breathing room with my salinity.

measurements of specific gravity taken with a hydrometer may require temperature correction in order to be accurate.

that is quite true. However I advocate using a calibrated refractometer which has automatic temperature correction.
