Is it ok to add salt for mollies to a planted tank?

I keep mostly mollies and platys, and the lfs guy said I should add salt for them. Will this negatively affect my plants? And what about my cories, loaches, and pleco?

Platys don't need salt, none at all. They breed like guppies in almost any water. Mollies are much more difficult to keep happy, being a brackish water fish to start with. I just don't keep any for that reason. And, salt in a planted tank isn't a good idea, unless you are aiming at a brackish water tank, where plant choices are very limited.

I'd just keep the water on the hard side and skip the salt.

Most domesticated Mollies can do fine in straight freshwater, though they'll generally do better in hard than soft water.

You might want to set up a separate tank for the Mollies. Platies can go either way, and the other fish are pretty forgiving, but if you can set up a low end brackish tank for the Mollies they will probably do better. Hard water at least, if you want to minimize the salt. The other fish (except Platies) do not like salt, and plants do not like salt.
I would not add salt to a planted tank. I would separate the fish and run each tank at the optimum conditions for those fish.

I kept mollies in my SW frag tanks for algae control. I've never had good luck with them in FW unless there was lots of salt and very warm water. Look at most of them in the LFS with clamped fins and the shimmies. I think you could eventually get a few to survive and do fine but I think the loss rate would be high.

I use RODI water and have nothing but molly and plattys besides my bottom feeders. They are doing real well in no salt. All of the fish I have are at least second generation

mollies and platies breed readily in many water conditions....and adding salt is bad for your plants

I had a black molly in my planted tank. Average KH and GH 5-7. Boy that fish looked like it was on steroids! I'm sure that it was due to it's algae diet. It was constantly eating algae.
