SeachemMatrix Carbon Tidal Filter - Activated Spherical Carbon Bead 190 ml

It is nice to have it pre filled but it hard to make sure everything in the filter is covered so the water flows through it.

Best carbon on the planet

Works as intended not much else to say.

Good

Works great with the filer and comes prebagged

Using in my Tidal 75 lagoon filter. Works great. Comes in it's own filter bag.

Great product for a great filter
