No more loudwolf sodium nitrate?

[Nick Steele]

Okay so I need to go ahead and continue dosing my tank for nitrates and phosphates and I was going to buy from loudwolf. But it seems that they don’t carry sodium nitrate anymore does anyone know why?

If not any other solutions I can make up?

There are other places to buy it, just by a Google search I found this:

Lab Grade Sodium Nitrate, 500g for sale. Buy from The Science Company.

Sodium Nitrate can be used to make Nitric Acid. It is soluble in water and readily forms colorless hexagonal crystals. It is a strong oxidizer but stable under ordinary conditions of use and storage.

I’ll have to keep looking as I wanted to get trisodium phosphate as well and shipping was free from loudwolf but $15 from the one you linked.

Is potassium nitrate a bad idea to dose nitrates with?

I used to use it, then switched to sodium because I was worried about raising the potassium level too high without having a test kit for it.

I'd recommend Amazon then, they have free shipping and low prices.

You can buy sodium nitrate and trisodium phosphate from Walmart with free delivery (https://www.walmart.com/ip/1-lb-Sodium-Nitrate-Fertilizer-99-Pure-Chile-Saltpeter-Gold-Metal-Refining-Industrial-Grade-Glass-Pottery-Enamels/105652076

No, I don't know if these are reef safe.

The MSDS for the tripotassium phosphate is here: https://savogran.com/pdfs/TSP_MS.pdf
It's 80% Na3(PO4)3 and 20% Na2CO3. If you're only dosing in ppb (ug/L) levels, then it's probably okay.

The sodium nitrate looks quite pure and has the same purity listed as analytical grade material from Sigma-Aldrich (see: https://www.sigmaaldrich.com/catalo...?symbol=608742&LotNo=OI2454&brandTest=ALDRICH)

That's awful news! I've been buying NaNO3 from loudwolf for a long time?

Has anyone contacted them to see if this will be permanent?

Reefers are starting to drain the supplies of uncommon chemicals. Sodium nitrate has been limited in the past due to potential to make explosives.

I would get food or reagent grade sodium nitrate. There are other sellers that have it, such as amazon. Potassium nitrate food grade is OK, but especially if you do not do water changes, I'd be careful.


Amazon has many brands of sodium phosphate, including Loudwolf.

I have emailed them not sure if I’ll get a response or not. If I don’t this week I might give them a call.

I might just have to suck it up and buy sodium nitrate and pay for shipping then.

Thanks everyone!

Let us know what they tell you please!

@Randy Holmes-Farley and @Coney Aldrich does this msd seem to show that it’s okay for reef tanks? Sorry I’m not good with this kind of chemistry.

I can order this from Walmart with free shipping. And 1lb should last quite a long time.

I think the sodium nitrate from Walmart is quite pure and very inexpensive. The certificate of analysis sheets you found suggest sodium nitrate is highly pure (99.6-99.9%) with only traces of water, chloride, sulfate and nitrite (if you are dosing at ppm, then you're introducing negligible impurities and the aforementioned impurities are innocuous). For comparison, loudwolf claims sodium nitrite is 99.6% pure, but there is no certificate of analysis provided to support this claim (since sodium nitrate is no longer sold, I can't find any information on Loudwolf's website).

I can't find a certification of analysis for trisodium phosphate, so would not recommend it.

I guess I'll just use ammonium nitrate then.

@Randy Holmes-Farley could one not use saltpeter(potassium nitrate) as a nitrate supplement?

Food grade as saltpeter is made to preserve food, just not sure if there are "other" things in saltpeter? Saltpeter should also be very easy to find in just about any grocery store.

The problem is that it's possible to raise potassium levels too high with it I believe.

It does not indicate a problem, but it also does not carry the assurance that food grade does.

Suppose that could be an issue if your not doing water changes. With normal weekly/biweely water changes, that shouldn't be an issue?

Food grade potassium nitrate is OK to use, but as we have noted, the concern is the potential to raise potassium over time, especially in a tank with little or no water changes. The boost to potassium is about 2/3 the size of the nitrate boost. So if you add 3 ppm nitrate per day, you are adding 2 ppm potassium per day. That's OK for a while, but eventually potassium may rise too much.

Thanks for the clarification Randy.

I personally use neonitro, but was just thinking out loud on what could be used as a proper alternative, and knew saltpeter(from being a chef) is mainly potassium nitrate.
