Well I dived into a 20L planted tank last week and got a wonderful surprise with flourite even after washing it throughly a few times to rid the dust. My tank looked like pond water for about a day! After it cleared, I decided to plant some of my swords and such - and the dust was so bad I had to plant some swords and grass one day. Then wait, and plant some more the next after it would settle again.
And now, I have dust covering the leaves of my plants! I was worried about the dust blocking the light for the plants. Is there a way to clear this up? Its like all my plants are dusty!
