This article documents a three-week experiment using ZooMed Mopani wood in a betta fish tank to achieve a dark water aesthetic. The author initially intended to use the wood solely for decoration, planning extensive boiling to prevent tannin release and maintain water clarity. However, the experiment shifted towards creating a dark water environment, ideal for betta breeding. A smaller piece of Mopani wood was used as a test to gauge its impact before committing to a larger scale project. The experiment tracked the wood's effect on water color and pH, providing insights into its effectiveness in creating a natural, darker aquarium habitat.The results demonstrate that even a small piece of ZooMed Mopani wood significantly darkened the water, achieving a portion of the desired effect. The author discusses the trade-offs between using Mopani wood (requiring boiling and resulting in tannin release) and commercially available alternatives that directly tint the water. A final rating and overall assessment of the wood's performance are provided, along with recommendations for users aiming to replicate a similar dark water environment for their bettas.
Pros And Cons
- Lowers pH
- Darkens water color
- Looks good in the tank
- Small piece purchased; should have gotten a larger piece

The Mopani Wood Experiment Begins
Three weeks prior, I decided to incorporate ZooMed Mopani wood into my betta tank. I acquired a small piece from Fishbowl Pets in Stanford, Connecticut – a store I highly recommend. My initial plan was to use it purely as a decorative element in my aquarium.
Before placing the wood in the tank, I planned to boil it for at least a month, possibly two, to remove tannins and prepare it for use. Tannins are naturally occurring substances in wood that can discolor the water. This initial preparation step is essential for maintaining water clarity if you don't want a dark water aesthetic.
Dark Water Aquarium Setup and Betta Breeding Attempt
My goal is to create a dark water planted tank, which is ideal for betta fish, particularly if I want to breed them. I have a male betta and two females; my hope is they will breed successfully in this environment.
The internet suggests that bettas thrive in darker water conditions. This experiment is a trial run to see how a smaller piece of Mopani wood impacts the water color and overall aesthetic of the tank before committing to a larger setup for my betta breeding project.
Three Weeks Later: Observing the Results
After three weeks, the Mopani wood has visibly darkened the water, achieving a portion of the desired dark water effect. While this is a small scale experiment, the results are promising.
I should have chosen a larger piece of wood for a more significant impact on the water color. However, the current setup provides a good indication of how the wood affects the water's appearance.
Alternative Methods for Achieving Dark Water
If you prefer to avoid the tannin release from Mopani wood or don't want to boil the wood for extended periods, there are commercial products available to achieve the dark water effect.
Brands such as Fritz and Kent offer products designed to tint aquarium water without the use of wood. These are viable alternatives if you're aiming for a specific water color without the extra steps involved in using Mopani wood.
ZooMed Mopani Wood: Final Verdict
The ZooMed Mopani wood successfully darkened the water and lowered the pH, creating a more natural environment for the bettas. Although a smaller piece was used for this test, it still provided a noticeable effect.
Overall, I give the ZooMed Mopani wood an 8 out of 10 rating. The main drawback was using a smaller piece, highlighting the need to choose a larger size for a more dramatic effect. For those wanting a natural way to darken their water and slightly lower pH, it is recommended.
