i am making 12 gallons of new rodi water  it is join into a 12 gallon food grade pail i have used for a while  the tds meter says 0  i test it with a hanna tds pen i do kno the tds gotes up after sitting in that pail for days ..so i make it up fast in like 24 hrs  with new salt  i put the pump in the pail and started it up  the tds has jumped to 14    no salt in yet just mabbe 4 gallons of 0 tds water..are yu guys testing as yu make it up?

I test quite regularly for phosphate, I do run the TDS meter in the buckets too, I have found the salt buckets don't seem to leech anything (well the IO ones anyway).  I test the white rubbermaid tub too once in a while just because I worry it will break down over time. 

I've said before, the water I used to keep in a blue brute rubbermaid bin was leeching ~100 ppm of phosphates into the makeup water (!).

My guess is pail isn't food grade.. Rodi water is strong, it strips plastics.

do yu think  the powerheads will leach some ?.....from sitting dry

I doubt it, they are used in tank with no problems that I have ever read about.

This topic comes up again and again. I think we should put together a more scientific test this fall. Get a clear plastic pail, a clean aquarium, a brute, a few diff 5 gal pails, a few TDS meters and maybe a a few heaters, and chart the numbers under controlled conditions.

good idea      i have the 12 gallon.a 5 gallon culligan jug and a 2 diff kinds of 5 gal pails      but im not home to do all the testing...i kno the galls aquarium and the 5 gallon culligan water jugs test 0 in a week

I use the brute garbage pail. Just tested it and got 3ppm tds.
Ive tested it before and always got 0. This is the first time i ever got a reading.
But i also may have slightly contaminated it with setting up the new tank.
I ended up using some tap water when i ran out of rodi water and the same water bucket was used back and forth.

I came across this article a while ago and it has some interesting things to say about phosphates we add to the aquarium (about food but there is a little on RODI water): http://www.advancedaquarist.com/2012/3/chemistry
Now hes talking about 0.05ppm in his RODI example so if you have something in the range of ~100ppm like salty then this may be of no help.

Also I would think that the manufacturers of powerheads/pumps wouldn't give a oop: about if their plastics leech a little and did you every use that pump for mixing salt (or in a tank) in the past, maybe that's your answer right there? (<-- I have no clue, I'm just throwing out suggestions  ;D)
