Betta Tea™ for Aquariums on the Surface

Betta Tea™ is a curated blend of crushed leaves, bark, and seed pods sourced from the native habitats of tannin-loving fishes. Sealed in fully compostable packaging, it delivers a concentrated release of humic substances and tannins into the water column without introducing additional botanical mass to your ecosystem.

It is formulated for aquarists who want to replenish the tint in their blackwater, biotope, or botanical method aquarium without adding more leaf litter or seed pods to the substrate. It is also intended for aquarists who do not like the look of leaves but understand the benefits of tannins for their fishes. Both blends share the same core botanical benefits, with the Maroon blend simply incorporating a bark with a higher antioxidant profile, making the primary difference between the two a matter of color preference.

Directions: Use one tea bag per 5-10 gallons of aquarium water. Each bag can be used in two ways. For a cold brew, place the bag directly into the aquarium or filter compartment and remove after 48 hours. For a hot brew, steep the bag in a mug of boiling water, allow it to cool completely, then add the brewed tea to the aquarium until the desired tint is reached. Hot-brewed tea can be refrigerated for up to two weeks. After use, the spent tea bag contents can be worked directly into the substrate as a detrital input, or composted.

Betta Tea™ for Botanical Method, Blackwater & Biotope Aquariums

Betta Tea™ was curated in 2021 to solve a specific problem in maturing botanical method aquariums: the point at which the water tint has faded, and adding more botanical elements is no longer practical. Each tea bag releases a concentrated blend of tannins and humic substances, replicating the passive leaching that occurs as leaves and bark naturally decompose on the forest floors surrounding blackwater environments around the globe.

Tannins and humic acids can shift water chemistry toward the acidic nutrient-poor conditions that popular aquarium fish have adapted to, but only when that source water is devoid of buffers. In aquariums with soft water, a slight reduction in the pH is expected, especially when used with reverse osmosis water. The blend of botanicals was intentionally selected to have a minimal effect on pH when used with tap water, making it accessible across a wide range of aquariums.

Betta Tea™ is equally suited for aquarists who prefer a tinted aquarium without the visual presence of leaf litter. Because we used crushed botanicals inside every tea bag, the tannin release is functionally equivalent to what a decomposing botanical contributes passively. The blend was selected for its diverse composition of beneficial condensed and hydrolyzed tannins, antioxidants, trace minerals, and vitamins that collectively help restore the natural water color and conditions your fish are adapted to. Tannins, especially those from catappa leaves, are widely associated with supporting the slime coat and their passive benefits during mild stress or early-stage disease recovery. However, the use of Betta Tea™ does not replace the medications needed to treat fish disease.

The tint will shift gradually as tannins naturally degrade. The Brown blend transitions from a hazy warm brown toward a clearer golden brown. The Maroon blend opens with a deep red-brown and moves toward warm brown as the tannins break down. Minor variation in tint intensity between bags is expected and reflects the natural variation present in real botanical materials.

Beneath the Leaves: From the Forests to You

The rivers and peat swamps that inspire Betta Tea™ are heavily tinted. In the blackwater tributaries of Indonesia, water moves slowly through layers of decomposing organic matter, stained by tannins leaching continuously from newly submerged leaves, bark, and seed pods. These environments are defined by what they accumulate. Canopy materials fall, soften, and release beneficial compounds into the water that help influence its chemistry, its biology, and the behavior of every organism living within.

The fish that thrive in these ecosystems have adapted to water that is heavily shaped by the seasonal flooding of the forest floor. As botanical method aquariums mature and tannin levels decrease, Betta Tea™ returns what the ecosystem is missing. Restoring the tint and humic substances. From the Forests to you.

Sustainability Note:

This product's packaging is home compostable. Just like the botanicals inside, it will break down naturally and return to the soil—because what supports your ecosystem should minimally impact our planet.

Not for human consumption. No preparation required.

This is a natural product, and slight variation in color, tannin intensity, and tint between bags is expected.
