Hey all,
My question is if I am going to add a small amount of salt to my freshwater tank, how much should I add -measuring in parts per thousand (ppt)


Thank you

The purpose for adding salt to freshwater tank is that it a) keeps the fish calmer and b) most fish actually live naturally in water with atleast some salt. You don't really add enough to make a huge difference.

Basically you need to go buy freshwater salt from the fish store or use kosher salt (NOT TABLE SALT, It will kill your fish or so I've been told) and the way the directions say on the bottle are 1 tablespoon per 5 gallons but you can only do it when you're doing water changes. You don't just want to add a ton of salt all at once add it when doing water changes until a certain point which you need a tool that measures salinity in water and I will figure out the salinity level you need in a bit haha.

Do not put in salt if you have live plants it will kill them.


EDIT: Also the ammount you add also depends on the fish for instance mollys like a LOT of salt but then there are some fish that do not really like it at all.

With the exception of treating ich combined with heat as per instructions, or to combat nitrite poisoning which requires a miniscule amount to achieve desired effect, aquarium salt should not be added to a Freshwater tank IMO. Long term salt exposure stresses Freshwater fish. Following the directions on aquarium salt actually DOES add enough to make a huge difference. Also, table salt will not kill fish. LFSs and aquarium salt manufacturers want you to believe this so they can sell you aquarium salt. The iodine and anti-caking agent are not present in sufficient amounts to cause harm, apart from unnecessarily adding salt to the tank.

Mollies do not necessarily like "a lot of salt". Due to their widespread distribution in the wild and overall hardiness in general, they can be kept in FW, brackish water, and even full marine conditions (given proper acclimation). However, aquarium salt does not replicate brackish or marine conditions; to achieve this, marine salt mix is needed as it contains trace elements that replicate sea water (or brackish water, in lower concentrations).

Yea I understand all this but the store uses salt, the fish are not in there for long because it is a store and they get sold. I would just like to get a ballpark estimate of how much salt (ppt) I should keep in the tanks. Any estimates would be appreciated thanks

I can see why fish shops do salt their tanks, (though, I hear this practice is a little outdated to other products on the market):
  • Reduce the chance of nitrate poisoning
  • wide scope parasite aid
  • irritate fish into producing more slime coating

EDIT: Oh! And you're not to use it in tanks with plants or scaleless fish as far as I know.

Ok look on the directions for the Aquarium Salt container it should list some messurments. I usually do half what it suggest usually 1/2tbs for a 5gal tank. But I only use salt anymore for treating illness. Other then that I keep my tank salt free. Though I can see the benifits but its still a risk you are taking. Even at a low level a Freshwater fish going from slight/possible high saltinity and going to none to little can damage the fish. IMO

I don't think your catfish will tolerate salt too well.

What you need to do prior to putting any aquarium salt in your tank, is to research each type of fish you have and see if they require (or can tolerate) salt. Many can't.

I have to ask, in looking at how you phrased yourself above, how much experience you have with fish. Your phrasing was kind of defensive and didn't come across as due to having knowledge of the species you were referencing.

You can learn so much here from these wonderful fishkeepers.

if the fish store usually uses salt don't they know their amounts already?

not to be rude just curious haha

Are you wanting to know how much salt for tanks at work or tanks at home.
If it's for tanks at work they usually have little containers of salt that sit right in the tank.

If your wanting it for your tanks at home you need to research your fish and see how much salt they can tolerate because some can't tolerate any.

My local Petco salts all their tanks(little containers sit in each tank) and they lose all the loaches they get after about a day.

To use salt or not to use salt in a freshwater tank has long and will continue to be a long disagreed upon subject. I personally do not use salt in freshwater tanks.

I agree that you should research about the fish before you add. The only reason I started at all (and I still only have enough in there for maybe 10 gal according to the directions in my 50gal tank) is because I know all the tanks at the store have salt in them.

Ok. LyndaB I am not defensive. Please read the entire thread. It's not my decision, the store I work at wants salt put in so I am following instructions. THEY ARE NOT MY TANKS.

Thank you

Thank you Carol, I do not practice using salt in my freshwater tanks either, but to answer your question the salt is for the tanks at the store.

Jersey, no they do not know, the old fish manager who ran things is gone. That's why this is so frustrating.

Thanks for your patience and the answers to my questions Tony.
If this is a major chain store I'm sure somewhere there is protocol for how much salt to add. Businesses just do not leave it to an employees discretion how much of any chemical to use.
If by any chance you don't find something telling you how much to use I personally would use just as little as possible. Just enough when asked I could say honestly there is salt in it.

I always wondered what those little containers were! Thanks Carol!

I have noticed upon close inspection many times the salt is in a container at petco in the tanks. An emloyee once told me they are sealed up and just in the tank so people will buy salt as a product. As stated by others, I used to use half the dose of salt in my molly tank.... but I phased it out due to tankmates.

Ok Carol, that sounds good. I think that's what I will do. Thank you very much.

Yep those are salt containers. One of the fellas that orders has quit ordering loaches except by special order because of the high death rate. I got their last three Dojos as they were gasping their last breath, took them home and slowly acclimated them to freshwater and you could just see their color coming back and see them perk up. I did lose one out of the group.
Sorry for the hijack

I hope this doesn't sound rude to Tony but this thread gave me a bit of a chuckle to myself. So many times people come in here and say "the guy in the fish shop told me such and such and it must be true 'cos he works in a fish shop". Now here is a guy who works in a fish shop coming on here asking what to do!

Not a new thing. It has happened before. Just sad he doesn't have access to more direction from work and glad he has the sense to ask for help.

Well I'm not one of those people who work in a fish shop and know nothing about it. I have been keeping fish for years and that is why I wanted a job there, to be with the fish and take care of them better than the other people could. Because I was a hobbyist before I worked there I understand how things work and so I don't lead people astray. And though I may appear to know nothing about fish I actually have a large knowledge base lol. I just ask specific questions that I am unsure of, but I can truthfully say that fishlore has taught me most of what I know.

I don't think you that you know nothing about fish, just because you asked a question. Nobody knows everything about fish, no matter how experianced you may be.

But I do think your question was a little ambiguous, so I think a lot of responders were under the impression it was for your home tank (which has a catfish), and not for the tanks at work. It's no big deal that your question was worded in such a way that it could be taken two ways, but just try to understand that people were trying their best to help, not judge.

Hey Tony, I respect your attitude. There is so much to know about fish keeping which is one of the big joys. There is always stuff to keep learning. The danger comes from fish shop employees who pretend to know more than they do. But I agree with Carol. If a shop wants salt in their tanks you would hope they would do so for sound biological reasons and therefore should have developed guidelines based on science, rather than just telling an employee to work it out for themselves. I'd take issue with your store management policy, not you, who are obviously trying to do the right thing.

It's really hard sometimes when we are not standing face to face with someone and we are trying to hold a sensible conversation Sometimes it comes out wrong - the question as well as the answers. Facial expression as well as body language are a large part of conversations and not having that can be hard but we here at FishLore usually get to where we need to be even if it's the long way around LOL
I think I would insist they give me some guidelines as to how much salt they want you to use. If for some reason something happens they may blame you for not doing your job right but if your following their guidelines they can't say anything.
