Give it some time. Clay based particulates may take a very long time to settle. You could try using a flocculant.

Tank has cleared fairly well.
But I was thinking about this as I have been gradually adding the API laterite gravel as funds allow. So in another 4 months or so I could see myself buying some more and running into the same problem.
On the one hand, the clay would be good in the substrate, on the other I have to rinse the gravel to get rid of the worst of it.
I wonder if adding a flocculant to the gravel just before I add to tank would help?
