None. The grains are small, but heavy. Even after vacuuming, the sand that does get sucked into the bucket, I rinse, and dump right back into that tank. It settles immediately. The Gouramis and the Yo-Yo's are grazers. The loaches especially move the sand and gravel around a lot. I have no issues at all with the sand becoming buoyant enough to be an issue with the filter.
