I've heard people use magic eraser to clean the diatoms off the glass
can anyone share their 1st hand knowledge and are there any chemicals in the sponge
I use the original mr clean magic eraser and cut into ~1/4 inch sheets and put it between my magnet cleaner. Works wonders, won't clean my glass without it.
You really shouldn't be using them for anything you HAVE TO rub more than once.
They do come apart and easily. It's an inert plastic, it's not biodegradable, but it can be eaten by your critters and cause any number of problems like the plastic particulates are causing in the ocean. Even the instructions say "do not ingest".
It's best to get something meant for the aquarium trade for your specific type of tank. I mean really, why take the chance?
If you have a random death are you opening the organism to discover gut content to be sure it's not abunch of plastic lodged in their GI tract or such?
Your concerns were addressed by numerous people and no where in your thread did you show any relationship with the use of magic erasers and random death.
But you can't prove definitively that it's not. So it's possible, and that's the crux of his argument. It's really weak, like the "you can't prove God doesn't exist" argument that says therefore he does, but it's not invalid.
