Matrix Carbon 6 Weeks In

I am now 6 weeks in with the current “dose” of Matrix Carbon in my tropical tank.

This time, testing against a glass full of RO/DI water i could see the faintest tinge of yellow against the pure clear water in the other glass.

Its not so easy to see on a picture, although you can kind of make it out around the very edge of the water on the meniscus…

Pure on the left, tank water on the right.

Its much easier to see when you could hold and adjust it against a light source.

As its still this clear i decided to give the current media another 2 weeks, and then call that the change out point. So in effect I'm getting 8 weeks use out of 80ml of Matrix Carbon.
