Reefstock Denver returns Feb 28-Mar 1, 2026 for its 18th annual event in the Mile High city. Combining some of the industries best coral vendors as well as manufacturers and LFS, Reefstock offers something for all hobbyists. New to reefing? We have workshops and speakers that will help you master the basics. Looking for that hot coral? Yep, we have those too. But it’s not just corals and hard goods!
Reefstock brings all things aquatic under one roof. Keep freshwater fish, aquatic or terrestrial plants? Interested in setting up a terrarium or vivarium for a new critter? Expand your hobby and start a new project by visiting our exhibitors while taking advantage of our educational speakers and workshops. If it can be kept in a glass box, you’ll find it at Reefstock.






Reefstock at its core is an aquarium expo, but there is so much more to be had than great shopping opportunities. We are a community! Plan on staying a few hours, the day or the weekend. We have an excellent slate of presenters to educate and entertain you. Sanjay Joshi will keep us updated on the recovery of his reef system. Sara Stevens will help us master coral disease identification and treatment. Tia Davis will help us identify beneficial macro algae and learn how to cultivate them. Marc Levenson will show us how to maintain our gear and help us understand where problems can occur in our water filtration systems. Sumer Tiwari will walk through some of his latest freshwater breeding initiatives. Shawn Hale will provide the ins and outs of setting up your first reef tank. Richard Ross will challenge our perceptions and give us an opportunity to rethink what we thought we knew about reefing. If that wasn’t enough, we’ll fill a few more speaker slots soon. Don’t forget the workshops!
