Where's the salt?

[trk1616]

So, the last 10 times or so I've added water to my tank, i haven't had to add any salt, only water, cause the salt level reads high. I figured it was high the first couple times and would do just water to level off, but they have read high every time for months. Everyone seems healthy, just not sure how it can continously be high if I never add any salt. Is this a problem?

Thanks,
TK

If you are only doing a top off, then you don't have to add salt.

When the water evaporates, the salt stays behind, and this will cause the salinity to go up.

When you top off with fresh water, it will cause the salinity to go down.

The ONLY time you should have to add salt to the water is when you do a water change, actually removing saltwater, and replacing it.

Also, it its too high, a way to lower it would be to remove some saltwater from the tank and add fresh water, with no salt in it.

If you do this, do it gradually, so as not to shock the system.

Theorertically, the only time salinity will drop is when you REMOVE water and replace it with fresh water.

Or when you dilute it by adding a lot of fresh water.
