Almond leaf safe for Nerite snails?

[Fin35]

Ok, and to buffer the acidic water for the snails With Indian almond leaf was thinking of adding eggshells to the tank for calcium.

I also really want to add another mystery snail, they’re so cool, but now I’m worried about them with the acidic water from Indian almond leaf. I’m also going to add some eggshell which will raise Ph, I have a testing kit coming Thursday, I just hope none of these things change the ph that quickly, will it cause and ph swings or do these things change ph gradually?

It's not likely to change the pH abruptly. But I would stager the additions if adding IAL or more items for antibacterial / black water, add something then wait a couple days and add something else.

If it is a pH increaser and a decreaser - IAL would decrease & egg shells would increase pH, probably would be fine for those since they'd cancel each other out.
