So I recently purchased a Chemipure Elite to help a little w my phosphate and keep in check as advised by a cpl of ppl on here bc I usually but the Chemipure Blue. I love this product and never have had any complaints. But this is my first time trying the Elite and when I opened and rinsed quickly there was ALOT of carbon leeching out. Like a lot. My hands were black. Is that normal for this product? And is it safe to put that in my sump?? If so much just came off on my hands from holding i can't imagine what will go into my tank. But I've never used this one before so idk if thats normal or not. Pls let me know! Thanks ;Happy
