I Captured AQUARIUM CO2 for 16 Days and This Happened!

Natural CO₂ production in freshwater aquariums is more powerful than most aquarists realize. In this video, we dive into how leaf litter, soil substrates, and microbial respiration generate dissolved carbon dioxide for plant growth, sometimes at levels comparable to some low CO₂ injection systems!

00:00 Intro
00:34 Experiment Design + Theory
03:12 Soil + Sand CO2 Levels
05:40 Leaf + Plant CO2 Levels
08:49 Final Thoughts

We’ll cover:

Measured data showing atmospheric and dissolved CO₂ levels
The difference between natural CO₂ production vs. injected CO₂ (30 ppm target)
How ingredients like Father Fish’s Aqua Preta soil supplement change CO₂ output
What this means for aquarium long-term stability

Whether you keep a natural, Walstad, or Father Fish–style deep substrate tank, this information helps you understand the hidden carbon cycle in your aquarium.
