Salinity level

Hello all,

I am new to this site, so hello and I need some advice. I just upgraded to a 90 gallon saltwater, my salinity level is 3.1, I have fish, soft corals and invertebrates. I was told this level is too high and do a 6 gallon water change with R/O which I will do today. My questions are what is a safe salinity level, and is this the same as the Specific Gravity. Any help will be GREATLY APPRECIATED!!!!!!

Thanks..............mardaman

Salinity level and specific gravity are one in the same. Mine usually stays about 1.024 in my 90 gallon.

You want 1.021-1.025 to be safe.

3.1??? Do you mean 1.031? If so, yes, that is too high. Most people shoot for 1.023-1.026...... personally I keep mine right at 1.026. You will want to bring it down slowly, not all at once.... if my math is right, each 6 gallon RODI change will bring it down about .002, so do a 6 gallon change every other day three times, which will bring you down to about 1.025.

And remember, when you are replacing evaporated water, don't use salt water. Use RO-DI water when topping off tank.
