How to Use for Best Results
-
Direct Placement: Drop 1 leaf per 10 gallons directly into your tank. It will float for 1-2 days before sinking.
-
The “Blackwater Tea” Method: Boil the leaves in a small pot of dechlorinated water to create a concentrated extract. Allow to cool and dose your tank gradually.
-
Maintenance: Replace once the leaf structure has been fully consumed or skeletonized (usually 3-4 weeks).
Pro Tip: For shrimp breeding, leave the skeletonized leaf in the tank. It provides a vital structural habitat for shrimplets to hide and feed on beneficial biofilm.
Indian Almond Leaves: Expert FAQ
1. How many Indian Almond Leaves should I add to my tank?
The general rule for standard tannins is 1 large leaf (6-9 inches) per 20 litres of aquarium water. For a deep “Blackwater” aesthetic or medicinal treatment (like fin rot), you can double this dose. If you have a nano tank, simply tear a single leaf into smaller pieces to avoid a sudden pH swing.
2. Do I need to boil Indian Almond Leaves before using them?
It depends on your goal. To release tannins immediately and ensure the leaves sink fast, boil them for 2-5 minutes. However, if you want a “slow-release” effect that lasts for weeks, simply rinse them under dechlorinated water and drop them in. Our leaves are triple-sterilized, so boiling for safety is optional.
3. Will Indian Almond Leaves lower my aquarium pH?
Yes. Indian Almond Leaves release humic and tannic acids that naturally lower pH. The effect is most noticeable in water with low carbonate hardness (KH). If you have very hard water, the pH may remain stable while the water still takes on a healthy amber tint.
4. Are these leaves safe for Snails and Shrimp?
Absolutely. In fact, they are a superfood for shrimp. As the leaves break down, they create a “biofilm” that shrimplets and snails graze on 24/7. They also provide essential humic substances that aid in the moulting process for crustaceans.
5. How often should I replace the leaves?
For aesthetic and medicinal benefits, replace the leaves every 3 to 4 weeks. If you are keeping them for shrimp grazing, you can leave the “skeletonized” veins in the tank until they completely disappear, as they provide excellent hiding spots for fry.
6. Can Indian Almond Leaves turn my water cloudy?
No, they should turn your water amber or tea-coloured, not cloudy. If your water becomes cloudy, it is likely a bacterial bloom from overfeeding or a new tank cycle. The tannins from Catappa leaves are clear, natural pigments that actually help clarify water by suppressing harmful fungi.
About IndianAlmond.com.au – From One Hobbyist to Another
Our Story: Born in the Blackwater
At IndianAlmond.com.au, we didn’t start as a retail business—we started as breeders. Frustrated by the brittle, dusty, and often pesticide-laden “mystery leaves” found in big-box stores, we set out to find a better way. We knew that for sensitive species like Wild Bettas, Caridina Shrimp, and Discus, “good enough” isn’t an option.
What sets us apart?
-
The Hand-Selection Process: We personally inspect every batch. If it’s crushed, moldy, or low-grade, it doesn’t make the cut.
-
Triple-Sterilized Guarantee: We understand the fear of introducing parasites to a prized colony. Our proprietary cleaning and drying process ensures every leaf is tank-ready.
-
Sustainability First: We only source from sustainable, pesticide-free groves that respect the local ecosystem.
Our Mission
Our goal isn’t just to sell you botanical litter; it’s to help you succeed in the hobby. Whether you’re trying to trigger a spawn, cure a sick fish, or achieve that perfect “Amazonian Glow,” we are here to provide the tools and the expertise to make it happen.
