Oh! Interesting. I didn't realize that there was such a product. Sounds like it's a dechlorinator with a bunch of other magic in it.

For your tank's salinity to jump 4 points like that, it means your change-water salinity was WAAAAY HIGH, probably in the high 30s. That would do it for sure. Especially if at that high a salinity the water temp was off and the salt was not fully mixed.

For instance, if you did a 33% of total water volume change and your tank salinity jumped 4 points, then you were 12 points too high or 1.037 in the bucket.

If it was a 20% water change, then your bucket was at 5 times four points too high or 20 points (i.e. 1.045 salinity).

Pouring in a large volume of super saturated high salinity water will definitely lead to some of the issues you've listed.

Totally agree Anthony, salinity and temperature is very important when adding new water. As well using RO or treated tap water is important. I always mix my water changes at least 24 hrs. before doing the actual WC.
