All Rubbermain BRUTE products are food grade. You can pick somethig up at Lowe's or HD. Then you can use a powerhead to mix and aerate it for 24 hours before use.

Okay, so a quick search revealed that some plastics are known to leach and others are not. My 5 gallon jug is a #3 recycleable container (stamped onto the bottom of the jug) and google reveals this means it is made from PVC which, from what I understand, is safe and should not be leaching anything. (Reefers use PVC for all their plumbing).

Maybe this needs a closer look as to why the test was producing high TDS?

#1 type plastics are to be avoided at all costs...
When subjected to harsh treatment, PVC is believed to release chlorine. Maybe the bleaching and whatnot caused a release of chlorine and that caused the TDS spike?

Mine have a #7 on the bottom and are also supposed to be safe. I did not do any bleaching till I found the tds. I took one jug the other day and cleaned it with bleach to try and get rid of the tds. I added water last night with 0 TDS and lets it sit for 1 hour and still had 0 TDS. So it appears that cleaning with bleach may have cleaned I will find out tonight after I get home and the water has sat for 24hrs. This may not even be a problem, it could just simply be salt build up, or calsium, etc... anything from using the jugs for years. The fact is in order to kill the algae in the tank I need to have 0 tds from my jugs to figure out the problem.

#7 is not as safe as people believe. Those do leach stuff.

Yeah I read several things saying that under "high temps" it can release stuff that is toxic to babies. Since that is what they use to make most baby stuff with, bottles, etc.

But it is supposed to be reef safe

Yes well now you are starting to learn that they don't have our best interest at heart. At "high temps" it can release stuff (to a high enough level that it can be noticed as toxic to babies) Like DDT it was safe right? The government as well as the company that made them said the stuff was safe... asbestos too... thalidomide (never made it to the US because of a Canadian in the US FDA) CFC's many prescription drugs and other things. There are many things that are considered safe at say 5 ppm but as time progresses the number changes and then it's considered safe at 5 ppb. But probably are not safe at any level it just hasn't been proven to be harmful at the new threshold. The way the system works is, it is safe until unequivocally proven harmful or has been on the market for 10-50 years and can be attributed to enough deaths. When they say something is safe often it isn't because they did a lot of safety testing but more the lack of evidence that it is harmful. California has more things that they say are unsafe then the rest of the US. The FDA will say that something is safe but California will say that it has to be labeled as harmful.

I know I kinda went off on a tangent here... it's just one of those things that get me riled up... and aquariums are slightly more fragile then our bodies.

Ok so I finally got home tonight did a water test on the water jug that had TDS. I washed out with bleach, rinsed it very well, let it sit and air out for 24hrs, and finally added RO/DI water and let it sit in the jug for 24hrs. The TDS was 0. So this weekend I will clean all 6 jugs the sameway! I will let you know if it works on all

All jugs have been washed with a 10:1 water and bleach mix. Set out for 24 hours, rinsed several times. All jugs are readinf 0 TDS!
