Is Your Biome Stable?

Is your tank really stable? How biomes change daily — and why no one knows the “perfect” bacteria! | Reefapalooza NY 2025

In this episode, Mark continues his conversation with Dr. Tim Hovanec, diving into biome testing — from how protein skimmers can alter bacteria to why test results can vary even around the same animal. They discuss when to test (since your biome changes throughout the day), whether biome testing should be like chemical testing, and why more diversity doesn’t always mean more stability. Learn what to do with your results, why no one knows the “perfect” bacteria, and how adding equipment or livestock can shift your tank’s balance.
