AllPondSolutions 黑碳 EF 外置過濾器濾棉

Installed these pads in my canister filter and the water clarity improved noticeably within a day. The black carbon material seems to catch fine particles better than the white pads I used before.

I swapped out my old foam for these carbon pads and the difference in water clarity was immediate. They fit perfectly in the external filter and seem to be catching a lot more fine particles than the previous ones.

The water's been noticeably clearer since I swapped these in, and the carbon layer actually cut down on the musty smell that my old pads never touched. I like that they trap gunk and polish chemically at the same time, so I only need one type of foam in the filter now.
