Amount of salt

[darthtang aw]

Going to back Bang up on this...I have seen when I ran my tanks around 1.027 I seemed to have less problems (not sure why). My current reef runs at 1.028 at the moment sometimes I measure wrong and it drops down to 1.027 based off water changes and levels...but I run high.

Hey Bang,
Not trying to stir it up if you will, but your picture is of the salinity at the surface. Salinity changes the deeper you go do to pressure right? Here is a chart I found that shows depth and salinity. While some corals are found in areas that are dry when the tide is out, most corals are below the water all the time. I know it isn't the best chart but it shows what I am questioning.

& evaporation at the surface.
The vast majority of corals we keep live no deeper than 50 feet. There are some deeper water corals available to hobbiests but they are fairly uncommon.
Good point on deep water salinity though

Yea, I was wondering about the depth on that chart. It seemed a bit like a moot point. Never the less another question answered. Thank you.
According to my cahrt the salinity only drops by .5 in the first 166 ish feet of depth. No real worries.

My fish gill harder at the higher salinities.

To expand on both of these regarding what somewhat wants to keep their tanks at, it depends on what the objective is. If your tank is mostly dedicated to the corals, and all you ever intend to keep are some clownfish, and maybe a chromis or two, running higher salinity is perfectly fine.
If you're plans are geared more towards fancier fish, Angels, Anthias, Butterflies, etc, definitely run the salinity lower. The vast quantities of choices of fish available now, can be directly related in most cases to collectors being able to capture fish deeper, then in years past. I think some of the depths some fish we kept are netted at, would really surprise a lot of people...

i never measure the salt... just pour it in, let it mix, and measure it and add more salt or RO accordingly
