Pozzolith water tank ecotoxicity??

Just to introduce myself I own 9.8 hectares in Central Otago with 1 hectare of grape vines some horses, willow trees carrex and rabbits.

Just picked up a tank that has had pozzolith in it. I'd like to use it for water storage. I've checked the MSDS sheets for pozzolith but there is no clear information about ecotoxicity.

Can anyone tell me what clean out is needed and any things they have found out about this stuff?

This PDF has quite a bit about water ecology worldaccount.basf.com/wa/NAFTA~en_US/Cat...09007af880125c1b.pdf
Or use this one and scroll down to the US and Canadian pdfs

Thanks, Stikkibeek. That's the information we needed.

Hi, here is the MSD www.aristonedesigns.com/msds/Pozzolith_NC534_MSDS606.pdf for new zealand. This might help. Cheers.

$trees, interesting, the safety stuff for humans, (obviously a chemical that needsto be handled with care, but unlike the US and Canadian PDF's I didn't spot anything about water ecology. It only had "no data available" so not quite so helpful.

Hi Stikibeek, here is the safety data sheet for NZ
