Hi again,
Just wanted to check in. I've added the salt as suggested, and will give it 2 weeks with a water change after 1.
Wondering if I should expect any plant damage? I assume 2 weeks would not be overly destructive but thoughts on this would be appreciated.
I have attached a pic to show the species I have. There is monte Carlo that is slowly taking on in the foreground also.
I don't know the names of all the plants but they are obviously low tech. No co2.

Thank you
