シーケム タイダル マトリックス カーボンメディア

I was skeptical about pre-bagged carbon, but this one fit my canister filter without any messy rinsing. The water cleared up noticeably within a few hours after adding it.

The pre-filled media bag made setup incredibly easy, and my water has been crystal clear since I put it in my canister filter. Even my usually skittish tetras seem more active now.

Fits perfectly in my Tidal filter and also works in my HOB from another brand. The pre-bagged design makes swapping media much cleaner than the loose carbon I used before. Only minor gripe is the bag could be a bit bigger for larger tanks.
