Looking for a Temperature/Salinity chart or calculator

[AZMSGT]

Here in Arizona the temperature swings from really hot to mild during the year. I am building a Mixing station in my garage and temps change from 110-40 through the year. While I can heat the water to stay at 77 during the colder times. Cooling it just isn't practical. Also my water coming through my RO unit is hot during the summer too. Inevitably I have to mix salt water in much hotter temps than ideal.

What I need is a chart that tells me at 100 degrees my salinity needs to be at Xppt so that when it cools to 77 degrees it's at say 35ppt and so on.

Kinda hoping someone has already created this. If not.. well then I have to do some cooking LOL.

Here is one with temperature in °C:

Here is a calculator:

Water Properties Calculator

Aquarium calculator; Estimate various properties of water at a given temperature and salinity.

www.hamzasreef.com

In this calculator, you can estimate other properties of seawater based on an assumed salinity and temperature (I'm not sure what you're trying to do with the data).

One more reference. I use this site a lot for other engineering work:

Seawater - Properties

Seawater properties like density, saturation pressure, specific heat, electrical conductivity and absolute viscosity.

www.engineeringtoolbox.com

The last reference is probably the best one as the temperature curve goes to 40°C (104°F).

Those are great. I will be honest was looking for something a little more accurate in the 75-110 degree range. I need more precision when mixing at these temps so I don’t send my tank into the gutter.

The last one should work. You would just need to interpolate. You can always make the mix a little on the low side of the salinity band, cool the solution to tank temperature, and do a final adjustment with salt and a refractometer.

The cooling isn’t going to be an option. I’m going to be doing auto water changes from tank in the garage. I’ll be moving 1/2g 4 times a day into and out of my tank so the warm temp of the water isn’t an issue. Just getting the salinity right is.

Ahhhh...I didn't understand that. Seems like you could definitely interpolate and then cool down a sample and check the salinity just to be sure.

What salinity do you run the tank at?

I can help you build a calculator, if you wanted.

Salinity calculator

A unit converter for calculating salinity in marine aquariums. The calculator supports conductivity (mS/cm), salinity (PSU og ppt), density (g/cm³) og specific gravity.

These are all excellent and I thank you.

Has anyone been able to adjust salinity using topoff and saltwater from an auto WC I was hoping to try something like that. I just need to trust the salinity probe first..
I adjust counterbalance air pressure based on motor current. I add or exhaust based on live readings.
