Cool Salt In Freshwater Tanks?

I have heard that some people add salt to their freshwater tanks.
What are the benefits?
At what level is the specific gravity?

Unless you are keeping coastal species that naturally live with a certain level of salinity in their water or are fighting certain parasites, I wouldn't add salt to freshwater tanks. Few plants appreciate it, and most fish commonly seen in the hobby do best in pure fresh. In cases of certain puffers, gobies, scats, monos; these are true brackish fish and require a certain salinity level to do best. Many of these can live in pure strength seawater (1.026) or water that is barely saline at all, others have more specific requirements. But without a good reason to, it's probably not a great idea for your average freshwater tank.

Thanks for the reply.
So if people keep freshwater puffers in their community tanks do they just their tanks at 1.00?

Depends on the species. Pea puffers I've always kept at 1.00. Puffers such as figure 8s will need the addition of some salt, but it will still usually be under 1.01.

So you think if the SG is slightly under 1.01 a figure 8 could be fine? What about the plants, rasboras, and tetras?
The reason I ask is because I really would like to add a figure 8 to my tank and that is what I have in it at the moment.

This is my tank thread.

Thanks for all the advice and help.

It's not a perfect match for the fish you've already got, sorry to say. I'm sure you could find a middle ground that both would live in, but it's kind of akin to putting a fern and a cactus in the same pot. They just have different requirements and keeping them both happy is easier done separately.

You think don't do it then?

Bump: A friend of mine has a Schoutedeni puffer in his panted tank and it has been going great for probably a year or so. Is because Schoutedenis can tolerate a lesser SG?

That's a freshwater species to the best of my knowledge.

I think you are correct. Sounds like they are just more peaceful I would guess.

Bump: So you think it would be hard to keep my current species with a figure 8?

Yeah, I do. You have a freshwater community tank and want a brackish water fish. I'd pick one or the other, personally. This is probably the biggest reason why multiple tank syndrome is a thing!
