Recent Question from Hobbyist:
Heavy metals like zinc and copper are not federally regulated and can be present in tapwater at levels that will kill shrimp and totally prevent brineshrimp eggs from hatching. Invertebrates are particulary susceptible to metal toxicity. See my book, pp 9-19.
EDTA chelates heavy metals on a 1:1 molar basis. To correct metal toxicity, you need to add an equimolar amount of EDTA. For example, my well water contains about 1 ppm zinc. This is 0.015 millimolar (1 mg/l divided by 65, which is the atomic weight of zinc). So I need to add enough EDTA to provide a 0.015 millimolar concentration.so you don't fear your brine shrimps becoming blue shrimps?
I have still some EDTA lying around...
Do you have an idea, how much I should add for a homebrew water conditioner
