[citation needed] During the 1980s, Sera continued to broaden its offering with new lines of foods, vitamins, and technological products.

Notably, the era featured the launch of the Sera Bio-Denitrator, the first device designed to biologically reduce nitrate levels in aquariums.

[citation needed][5] Sera's Nature brand of fish and reptile food products include insect meal-based products (Sera Insect and Pond Insect), natural colored staple foods (Vipan and Vipagran), Spirulina-enriched tablets (Spirulina Tabs and Plankton Tabs), green-matter rich algae crisps (Catfish chips), and treat mixes with freeze-dried organisms (GVG Mix).
