what is a braun coffee filter made of?

i have a braun coffee filter which i use to remove traces of salt water from brine shrimp (which i feed my hydra with). i know already that copper or any other metallic element has a negative effect on hydra and various other metazoan creatures, and it recently came to my attention that my filter might be made of copper. for any lovers of braun coffee, do you know if the company uses copper to make their filters? note: the filter is a gloden brownish color, very resemblant of copper. thanx for any help!

What are these weird things swimming in my fresh water tank? Part 2?

I posted a question a few days ago about my angelfish (marble angels) and I said they had laid eggs and now all of the eggs are gone (they ate them) none hatched. Well there are these weird off white “things” alive and swimming around in my tank. At first they looked like lice? They are so tiny its hard to really tell what they are even with a magnifying glass. Well now they are taking the form of something that looks like a tiny tiny inch worm. (Again, very hard to tell even with a magnifying glass) They are crawling around on the glass, and the other form (looks like lice) swim around in the tank. One person said maybe it is a “Hydra”? i’m not sure since its hard to tell what these things in my tank look like. If they are Hydra, I thought someone said you had to have brine shrimp to cause this and I dont have any. ANY THOUGHTS WOULD BE HELPFUL.. Other than that I’m gonna try to kill the beasties before something happens to my fish who seem clueless.
