It was just uploaded by the channel Fancy Shrimp, the amazing video “E I Salts (Fertilizer) – Does the minute amount of copper kill shrimp? ( Part 1 )”.
As informed in the description by Fancy Shrimp: “This is the first in my series of myth-busting videos to see whats true and whats not in the world of shrimp and fish keeping.
Seeing as copper can kill shrimp, do minute amounts in fertilisers (specially E I Salts) kill shrimp? I think not and will be putting this to the test.
