Don’t seem to be able to watch the videos. Has something changed ?

Try using the mobile site instead of the app and see if that works. There are quite a few different issues with the new site and different OS.

Soooooo...turns out water temp makes a HUGE! difference in salinity! 1.029 gos to 1.026 when heated from 50 to 80 degrees! also my DOS takes out 4% more salt water then it puts back for auto water change Thus i need to add 1.032 salt water just to keep salinity at 1.026. Let me know if you think my math is wrong please.

If I watch on my phone(Android) I have to download the data to chrome and watch it in my gallery.

I think that it isn’t that the salinity (as in how much salt is in the water) changes. It’s that the temp affects the reading because it it’s a measure of density / specific gravity.

Maybe try something like this?

Marine Salinity Tester - HI98319

Hanna Instruments HI98319 Marine Salinity Tester measures conductivity (EC) to determine the salinity of natural and artificial seawater within seconds.

Use that to measure both the new SW and the tank and just adjust the new stuff to match the level you want.

I kinda get where your coming from but no 1.029 salt water when heated from 50 t0 80 degrees ...goes to 1.026...so when i take into account that my makeup water is 50 degrees and my DOS is 4% shy i need to add 1.032 salt water!
