Superfish 超級活性碳

I was amazed how quickly the charcoal cleared up the haze in my tank after just a few days. Definitely worth the swap from my old carbon pack.

Water's noticeably clearer after two days, which is what I wanted, though the bag is a bit smaller than the cartridge it replaced. I'll probably need to swap it out sooner than expected, but for the price it does the job fine.

The carbon granules seem fine, but I didn't notice a huge difference in water clarity after a week of use. It does help with odor control, though. It's okay for the price, but I've had better results with other media.
