In the last 2 years these bags are disintegrating/ ripping within 4 months leaving my sump & tank riddled with loose carbon that has to be vacuumed out much less the sand bed be replaced. I have a 240g fowlr tank with a Moorish idol, regal angel, blue face, tusk and other high end fish. After 25 years using Boyds, I am boycotting Boyds Chemi-pure going forward, there are many other products out there. Anybody else in the same boat?
