Plastic container for ato

[xmjxflipx]

@Randy Holmes-Farley i use w food grade bpa free pet food container to hold my rodi. I did an oceamo icp test and it brought up antimony at 7.5 micrograms. First, what can be used to remove antimony from the reef as far as media or product and second is, so you think thr antimony is being leeched from the plaatic food grade container as i have heard rodi that is exposed to some air becomes acidic and i assume maybe it has broken down after using it as an rodi container for over 6 months. Its not fully sealed and has a small opening in the front for thr wires and the ato tubing.

If plastics were a concern i was wondering how come reefers. Use those huge hdpe towers to store and mix saltwater. I assume maybe because its enclosed and not open to air?

Any suggestions such as not using ato and using acrylic and glass and chunking thr plastic? Lol

I just use a 5g home depot bucket.

Yeah i just bought an acrylic ato... I was considering glass but still close to same price

I don’t know where antimony might be coming from. I’m also not sure 7 ppb is an any concern. The values I see needed for toxicity are far higher:

Effects of antimony on aquatic organisms (Larva and embryo of Oryzias latipes, Moina macrocopa, Simocephalus mixtus, and Pseudokirchneriella subcapitata) - PubMed

Antimony is widespread in aquatic environment. Trivalent forms of antimony are known to be more toxic than other chemical species of antimony. In the present study, antimony potassium tartrate (APT), the trivalent inorganic forms of antimony, was selected as a test antimony compound due to its...

IMO, HDPE is a good choice for water storage of all types, and the impact of CO2 on it is not a problem in general.

You store your RODI water for 6 months!?

I found this: https://www.faunamarin.de/en/knowledge-base/antimony/

Removal: Partial water change, removal of decoration, filtration via Powerphos, Phos 0.04, Zeolite

The metalloid antimony gets into the aquarium water via unclean plastic packaging and inferior PVC parts (piping) and can be removed from the water with our Phos 0.04. A value up to 10 µg/l(0,26 US.liq.gal.) is tolerated in the aquarium; as for many metals, this is also the limit value in drinking water. Antimony is also found in some frozen food. Therefore these would also have to be checked if the measured values are too high.

I store my RODI in Hedpak HDPE container & ATO in Rubbermaid 1g pitcher. ICP has not shown elevated antimony.

Best of luck!

I believe they are simply speculating on an allowed level.
