I have a mixing station I bought used made of 55 gallon Brute barrels. Markings on the bottom classify the plastic as LDPE (Low Density Polyethylene). For reference here is a link to the barrel in question Rubbermaid White 55 Gallon container
For the past 2 months I have been struggling with Cyano and Dino's and I have been trying to let them run their course performing 20-25 gallon water changes every week but instead of getting better it was getting worse, I bought a handheld TDS meter and found the RODI water in the bucket I was using for top off and salt mix was reading between 5 and 6. I emptied and washed the barrels and made a new batch of water and the reading straight out of my RODI and in the bucket was 0 so the TDS was coming from sitting in the barrels over time.
Should I be looking to change out my barrels for something else? I can not find anywhere that says LDPE is considered ok for potable storage of water although it used in food and juice packaging.
Thoughts, should I be looking for something different for my mixing station? Does your plastic storage and mixing barrels add TDS to your RODI water and this is just normal? I typically top off my barrel every week so water is always sitting in it.
Also if anyone knows of a local place that sells plastic barrels that are better for mixing station/water storage please let me know
