Not according to the tables published by Horst/Kipper and others.
The 0.5 to 1.0 KH increase should cause a small pH increase.
No, not much oxygen is being produced.

My mollies thrive in a 29 gallon with 2 grams/liter marine salt. Java
moss, java fern, hornwort and water sprite all do well. The water is
very soft at 2 to 3 dH. I've read that Cryptocoryne ciliata, Anacharis,
Elodea densa, Hygrophila polysperma, and Vallisneria gigantea also do
well up to and above specific gravity 1.0023.
Sorry, my mistake. That's 2 grams/gallon although the plants supposedly
can take more.
