food grade containers for water storage ???

(question #1 )if a plastic container has HDPE stamped on it, is it a so called food grade container approved for water storage? EXAMPLE: look on the bottom of your bucket of instant oceans reef crystals. i believe it is of recycled material because it has a 2 in the middle of a triangle of arrows.

(question #2 )is the bucket that the salt comes in, safe to store water in and not cause ammonia spike?

(question #3 ) would cleaning my brute trash can with bleach keep me from testing positive for ammonia when testing stored ro/di water?

(question #4 ) how do you clean water storage container with bleach(clorox) without contaminating your reef tank?

if you are wondering why all these questions please read my thread in chemistry called (amazing discovery today)
please help, i'm in a bit of a pickle here... thanks, brian

 

Pure bleach. Once the bleach is dry the active ingredients are permanently gone.

 

HDPE doesn't mean it is food grade it tells you the type of plastic it is high density polyethlyene I believe food grade means just that food grade.

I store my RO in my old salt buckets...

Brute cans are known for leaching PO4 I can tell you that...
If you are seeing NH3 are you sure your municipality is NOT using chlorine but chloramines?
If you filter tap that is treated with chloramines through a RO you will take out the Chlorine but you then leave behind the NH3, I would call your water plant!!!

Bleach the container and then wash it out well!! If you still are worried use a water conditioner that contains either sodium thiosulfate or sodium hydroxymethane sulfinate to remove the chlorine and NH3...

Good luck!

 

can you please be more specific? i don't mean to be a pain in the a$$, but i really don't know how.
aren't you suspose to dilute it in water? do you take a rag and rub it around? or do you just let it soak?

 

my tap water comes from my personal well. when i test my ro/di water straight from the exit tube as it falls in my trash can, the test shows zero ammonia. i'm assuming it has to be the brute trash can. i have a couple extra salt buckets but will have to bleach them. how do you clean with bleach... do you dilute it and let it sit or do you actually wash with it???
i feel stupid because i don't know how, but i really don't know how

 

I would just fill the bucket with water, add some bleach then dump it out... If there is deposits just scrub them off with a clean rag or similar algae pad for aquaria use.

You can then rinse the bucket really well, or fill it and add a dechorinator or let dry, the chlorine will eventually evaporate out.

The brute could very well be leaching NH3... Google food grade containers and you will find many sites where you can order the food grade water holders.
