Sucked these from the sandbed. Not sure if worth treating or just leave it be. Any advice welcome. Thanks.

I would try to pull as much out as you can. Have you test for phosphates? How long have the tank been up?

 

[bubblemytip]

Thanks. Phosphate is .04ppm, Nitrate 1.5ppm. Running zeovit. Tank details here:

Here is another photo of the stuff in situ rather than in a beaker.
