What you want is Reagent ACS grade chemicals. Google or eBay for places to buy them. These are the types of chemicals virtually all aquarium companies use to formulate their products.
Sorry this Doctor and associated troll a very poor exmaple and something that reduces any sense of credibility rather support your contention.
We've use ag grade for over 15 years without any incident at all for aquariums. I've kepts rare fish and wild fish for these tanks, shrimps and other sensitive creatures.
Several thousand folks, past winners of contest, all have no issue, now why might that be?
You and the Doctor claim this is a reason, I challenge you to show support
for this contention, no one has ever supported their position that this is a reasonable issue.
Stop making up mythswhere non exist.
If you have any real support or practical proof of any type, feel free to show it.
Otherwise I will continue to punch some rather large gaping holes in your contentions/position till you offer any real support that makes any sense.
It's not personal. But I do not like myths and I know this issue not to be true
and anyone else that's been using ag grade stuff for the last 15 years also knows this.
