It is the best thing I ever used in my old turtle tank I tried lots of media in it. I understand why you all say it’s no good and I think you’re all right. I found it use to go in to a clump and get a like jelly on it whether that gel like stuff was any good is beyond me :S does any one know what the jelly is? But the water tests always said the water was really good when it was in there.
another thing too think about some of those pads are dipped into a formaldehyde
to preserve them and make them stiff
