Salinity 1.026??

[JOKER]

So I am just wondering where most SPS tanks run salinity? I shoot for 1.025 now, but have ran it higher. Results seem the same. What are benefits of keeping it higher? CAL RX when needed. Thanks

I'm a layman.

Easier to figure correct alk and the rest of the ingredients. As salinity changes density changes. Alk changes. Cal changes. Etc.

So it's a standard to keep the rest realative.
NSW is about 35ppt so 1.026. Water it down and you water down your alk reading.

What @saltyfilmfolks said. Salinity changes all of your parameters. I keep my tank at 1.026 so it helps keep the Ca and Alk up. You can see this chart on the Red Sea blue bucket I use...

Makes sense. I also use red sea blue. I really like how it mixes, and it keeps for a month in my AWC with no issues. I think I lose .5 alk, and very little in calcium. I mix it for a few hours and just let it sit. At 1.025 I am only dosing 4-5 ML day 2 part to stay at 420 cal, and 8.1 ALK. I change 2 gallons a day with AWC, but the coral are all fairly small. I think I will raise it back up over a few days and see if results change. Thanks!!

Mine runs anywhere between 1.024 to 1.026. Usually somewhere in the 1.025 range.
I do daily auto water changes. If the new mix isn't exactly the same as the tank, I might see slight drop or increase over several days.
I don't sweat it and just correct it next batch.
I don't notice any major changes in my Alk.

My AWC actually removes a little more water than it replaces right now so I compensate with salinity in my storage by bringing it up some. I check it 3-4 times a week just to make sure its between 1.024 and 1.026. My motto as long as it doesn't change too fast they can adapt, and everything seems happy so far.

Exactly that.

I try to keep mine around 1.026, it'll occasionally drop down to 1.025, but I hang right around in that area.

Salinity does not equal specific gravity, these are measurements of two different things. This is why on the bucket it says S.G at 25C and not salinity at 25C. Specific gravity is a measurement of density and we usually measure salinity with ppt and this represents the amount of dissolved salts in the water. This article provides some good charts about how salinity and specific gravity vary with temperature and are related but not the same. https://www.algone.com/salinity-and-specific-gravity-guidelines-for-the-saltwater-and-reef-keeper
