Giant Alder Cones
You will receive either 10 or 30 giant alder cones. Giant alder cones are the same as alder cones just a larger variety. The giant alder cones will release more tannins into the water. These cones are very similar to Indian Almond Leaves and act in a similar way. The cones are beneficial to shrimp, bettas, Apistogrammas and Corydoras species for their healing properties and ability to lower the pH.
Key Features
- Provides natural food source for ornamental shrimp
- Releases tannin into the water which contains healing properties
- Lowers the pH slightly
- Anti-fungal properties to help fight off infection
- Creates additional hiding places to reduce stress in baby shrimp
| Quantity Available | Usage |
|---|---|
| 10 cones | Small aquariums or beginner setups |
| 30 cones | Larger tanks or established communities |
FAQ
Do giant alder cones lower the pH of the water significantly?
Yes, they lower the pH slightly, which is beneficial for species that prefer slightly acidic water. The effect is gradual and depends on the tank size and water volume.
Can giant alder cones be used in tanks with fish other than shrimp?
Yes, they are safe for bettas, Apistogrammas, and Corydoras. They are not recommended for fish sensitive to tannins or acidic conditions.
How long do the cones last in the aquarium?
The cones break down over time and typically last several weeks to a few months depending on water flow and tank conditions.

Jack Peters –
I added 10 cones to my 10-gallon tank for my shrimp and bettas. The water turned slightly brown and the pH dropped a bit, which is exactly what I wanted. My shrimp seem more active and the water looks cleaner. Great for beginners.
Michael Quinn –
Used 30 cones in a larger tank. The tannins helped reduce fungus in my shrimp. The hiding spots are useful for baby shrimp. A little slow to break down, but worth it.
Elizabeth McGrath –
The cones are easy to add and work well with my Corydoras. The anti-fungal effect helped during a minor infection. pH dropped slightly, which is ideal for my species.
Lily Newman –
The cones released tannins as expected, but the effect was slower than I hoped. Not a big issue, but might take longer to see benefits in a small tank.
