(My first post after some time lurking this forum)...
Is it possible to use an algae scrubber as complementary filtration in a large system (1000 liter / 275 US Gallons) already using bio pellets and skimmer for filtration? How low nutrient levels (N&P) can such system go without starving the algae in the algae scrubber to death? Does the algae scrubber remove anything else than N & P that the aquarium would benefit from?
