No not particularly. I did get a small diatom bloom from switching to new sand, but that's winding down now. Combination of "excessive" water changes, a mag float, and the recently added clean up crew solved that problem.
However, since I've been using nonRODI water I have had a small amount of hair algae. The clean up crew made short work of that, and I'm sure the few remaining patches will be eliminated soon. I've also started using a phospate removing pad in the filter, even though my phospates are fairly low from the tap to begin with.
