Salinity Rising?

[baron1282]

I just can't figure it out. Why is my Salinity rising? I mix my water to 1.23 Salinity. I mix it in a bucket and let it sit for a few days before I do a water change.

I was just buying my water at the LFS, but they stop selling it. The water was always at 1.24 Salinity.

As of right now my Salinity is at 1.26. I don't get it, shouldn't it be around the 1.24 or 1.23 mark? I don't top off with Saltwater, I top off with R/O freshwater. I use R/O water when I do water changes. I only use R/O water.

I than test my tank and the Salinity is at 1.26. Why would that be? I let my water sit for a few days before I change it. I mix and let it sit. I test the water before I put it into the tank and it would be at 1.23. Than once it's in the tank it's at 1.26.

I even did a 10% water change with just freshwater and it didn't help. It's still at 1.26. I don't get it. I thought my meter was broken, but it gives me correct readings for everything else.

What are you testing with? A refractometer (highly recommended) is not affected by temperature like swing arm hydrometers.

Hydrometer. I will look into a refractometer.

bring a sample to your lfs they usually test water for free and most have a refractometer hope this helps best of luck
