Salinity

[lm]

What salinity are most reef tanks kept at? tia

 

[simm]

1.022 - 1.026 is acceptable. I keep mine at 1.026. A lot of corals like a higher salinity IMO.

1.024-1.025 is ideal for a reef tank

35 - 36ppt.

 

[wolffam]

1.024 - 1.025

Bangguy's 34-36 ppt is the best advise because the specific gravity changes dependent on the water temp. but the ppt remains the same. It is also important to know the temp calibration of the hydrometer you are using.
Find a conversion chart to get the ppt based on specific gravity and water temp. this will give you the ppt
