Expiry date for safe and prime

[GundamCichlid]

Hi,

I am just wondering if there was an expiry date of the prime and safe???

Planning to buy the big one but worried if the product would be expired before I use it or the product is not working after certain time after the botle is opened

Anyone know about this expiry product???

Thanks

i dont think it has got an expiry date ,i all ways buy 2ltrs of prime and it last for months

1ml treats one gallon so it lasts a long time

I checked my bottle. It has no use by date. It contains complex hydrosulfite salts so would last for years.

...don't go by the smell either!! hahaha

[Aquaholic]

yeah its supposed to stink

It's a lovely odour........worth opening the cap and sniffing from time to time.

just keep it out of direct sunlight etc... cool shady place and all should be fine.

Hello G,

Thank you for your questions. There is no shelf

life on either Prime or Safe, therefore, there is no

expiration date on either product. They will be just fine

to use as long as there is product remaining. Let us know

if you have further questions, and have a great week!

Hi, I am just wondering of I place Seachem Purigen in my pre filter canister before it goes into my main canister filter. Will the Purigen starve the beneficial bacteria housed in my main filter?

[Link2Hell]

the Purigen won't have a negative effect on your bacteria it will improve water quality by removing impurities

According to this article, PRIME & SAFE converts to Sodium Thiosulphate and also explains that sulphurous smell.

I've heard similar things but never tested myself even though that would be easy. 

Sodium Thiosulphate can be bought at most swim pool supply /shops including Bunnings.

I bought a 20Kg bag of ST crystal that worked out to be less than $5 per kilogram. One of my tanks is 100,000L which would need 300gm (at 4ppm chlorine/chloramine).

I fell deep down into this rabbit hole of saltwater aquarium geeks & water chemistry. 

They seem to show PRIME doesn't remove ammonia in analytical tests and practical tests.
