Deteriorate around a month
These products work ok for the smaller filters but when used in a real filter like the Tetratec 500 they literally deteriorate and fall apart around 1 month. Extremely expensive when using 4 of them and you have to replace them in like 2 weeks or they break down in your tank. Added 4 new ones and went to replace the carbon a month later and they fell apart as I pulled them from my Tetratec filter releasing all of the waste they captured back into the tank. I would not recommend these products ever.
