Hey guys,

Ive read the sticky about using "No salt" for potassium supplement.

I happen to have some in the kitchen and it contains :
Potassium,Chloride,Ammonium,Phosphate,Calcium,Magn esium and Sodium?

Im just double checking to see if the one Ive got is safe to use?

Im a bit worried with the ammonium- is this thing like ammonia?

Thanks

Comes in a white cylinder about 6 inches high and 2.5 inches across?
Says "NoSalt" in green and red letters?
Has three different lid settings: Shake, Closed and Pour?

That's the one you want. Sorry, I can't seem to find an image of it on the Net. :(
It works well. Enjoy!

I use NuSalt (http://www.nusalt.com/faq/index.html) instead of No-Salt.

"Nu-Salt contains potassium chloride, potassium bitartrate, silicon dioxide and natural flavor derived from citrus fruits and honey."

Less extra stuff. I'd check that out if your concerned about some of the other ingredients. Haven't had any trouble with it.

Ammonium is non toxic

Ammonium is non toxic

well I wouldn't say that... perhaps it's at a low concentration. add a little to water and use an ammonia test kit to see ifthere is any.

Ammonium is ammonia with an extra hydrogen ion.

NH4+ --> NH3 + H+

In an acidic tank (pH<7) you have ammonium because of all the extra H+ ions floating around. In an alkaline tank (pH>7) you will have ammonia because all of the H+ ions on the ammonium will get stripped off to bind with OH- ions and form water.

Ammonium is not toxic. Put it into a tank with pH>7 and it turns to ammonia and is now toxic.

Aside from the ammonium, are you sure you want all that other stuff and in what sort of ratios? Some folks want to add a lot of that stuff, others not so much.

Seems a little too broad spectrum

Everything other than potassium chloride will only be present in very small amounts. IMO you can use it safely, but keep up with your water changes in case you're overdosing (we don't test for potassium). I use NoSalt as well, but mine doesn't have ammonium phoshpate. In any case, I don't see how the proportion of it would be so large that 1/4 to 1/2 tsp would include so much that it would harm your fish. The Ca, Mg and Na will be fine as well. Think of it this way, even if you were adding 1/4 tsp pure NaCl, it wouldn't really change your sodium levels, and what you're adding is mostly just KCl anyway.

Thanks everyone for the advice and info !

I might go get a new one with no ammonium and other stuff in it just to be safe since I noticed mine has already out of date since 2001.

Thanks again

Do you mean the salt? I don't think that you have to worry about your salt expiring!:eek: You may just need to add a little extra to compensate for water absorption.

I agree with Starry on the proportions of the other stuff being so low you needn't worry. Besides, if your tank is cycled, it's constantly processing ammonia to nitrate. Any tiny amounts you add through the occasional fert. would have no more effect than a slight increase in in tank ammonia production, say overgenerous feeding one day. ;)

It says on the box it has 3g ammonium per 100g and 39g of potassium per 100g,so I guess its not much compared to the potassium amount.


I don't think that you have to worry about your salt expiring!

But wouldnt the contents/values in the salt not be the same anymore when it has expired?
I was thinking maybe the potassium may no longer be there?

Im just assuming off course I know nothing about these stuff :confused:

So, it's 3% ammonium. I think that since you're using exceptionally small amounts, it's not something that you can't handle. Like I said, your nitrifiers are dealing with ammonia all the time.

They likely mean that it's 39g of K per 100g solid. 52% of the mass of KCl is K, so 39g of K is equivalent to 75g of KCl. Seems a little low, if you can find something that is more pure, it may be worth it, just to get more bang for your buck, so to speak.

As for the expiry date, don't worry about it. KCl isn't going anywhere. It melts at 775oC and doesn't boil 'till about 1500oC, so you needn't worry about it evaporating. It will absorb water over time, so yes, technically the proportions of things will decrease as water increases, but the same compounds will still be present. It's just that since the amount of water has increased, there will be less KCl per gram than before.

That's interesting though, I just checked what I've got, "NoSalt", Ingredients: KCl, potassium bitartrate, adipic acid, fumaric acid, silicon dioxide (sand), and mineral oil. No ammonium.

Also, it's 96% KCl (650mg K per 1.3g serving).

I were I you, I would be tempted to find something more pure. But I don't think that you need be concerned about health, it's just easier to dose if you can assume purity.

Mine's exactly the same. I think I remember checking some MSDS before using it, but I wasn't really concerned.

I also wouldn't worry about the expiry date, use it up since you already have it. It should last you pretty long. In the mean time, you can look for something better if you really want, but start dosing this now, your plants probably need it. I've been tempted to snatch some pure KCl from work, but this NoSalt looks like it'll last me a few years as it is.
