Salt in a planted aquarium? Yea or nay?

Most fresh water plants do not react well to long term use of salt in the water table.
Your fish should develop a taste for them. I'm surprised that they haven't already.

dont put salt in your planted tank....

The previous posts are good advice, but sometimes you have to use salt for other reasons, such as parasites. The plants you listed can tolerate a bit of salt, but it might not be enough to take care of the worm problem and this is a huge tank (i.e. lots of salt).

you've probably got 'nematodes'. you don't need salt to get rid of them. they commonly show up in tanks with an excess of food and most are introduced to an aquarium from other aquaria with live foods like black worms, live plants, or anything else moved from an active aquarium that has them. If a lot of residual food is left in a tank, including dead and dying fish, snails, other animals, and plants, then a few planaria may divide into hundreds very quickly. they usually reproduce by asexual fission.

If a tank is found to have planaria, they can be controlled by a good vacuuming of the gravel and better tank maintenance. to remove nematodes from a more heavily infested tank:

1. Set out bait like meat in a mesh bag. remove the bait a few hours after the lights go out on the tank. it should be covered with nematodes. throw away and repeat until the population goes down.

2. add nematode eating fish to the tank. such species include the paradise fish, betta, pelvicachromis pulcher and many species of gourami

3. vacuum the gravel very well and do a 50% water change. often, nematodes proliferate when the tank is too dirty. this will remove not only some nematodes but their food source as well.

4. reduce the foods added to the tank. nematodes often proliferate if too much excess food is provided.

In my experience I've found salt kills off plants quicker than it does undesirables like parasites and fungus.

I had a less than brackish aquarium (can't imagine more than 1.008 to 1.010) and any plant I put in would die within hours.. it took a quite few water changes before they got healthy again.
