ANS Casuarina Cones Aquarium

ANS Casuarina Cones – Natural Aquarium Botanicals (Reduce pH Level + Tannin Blackwater Effect)

Want a more natural and healthier environment for shrimp, betta, and softwater fish? ANS Casuarina Cones are 100% natural aquarium botanicals that slowly release important tannins and humic substances to create a tropical-like blackwater environment while helping to reduce pH level gently.

Natural pH Reduction (Softwater Support) – Casuarina cones release tannins/humic acids that can naturally lower pH and create blackwater conditions, ideal for low pH setups.

Blackwater Look + Stress Reduction – Adds a natural “tea tint” which many softwater fish prefer, making the tank look more natural and comfortable.

Baby Shrimp Hideout + Biofilm Grazing – The cones act as shelter for baby shrimps, and biofilm grown on them becomes a natural food source for shrimplets.

Helps Create a Natural Biotope Tank – Great for shrimp tanks, betta tanks, and blackwater aquascapes (nature style botanical setup).

Natural Antibacterial / Anti-fungal Support – Casuarina cones contain humic acids and tannins that are often linked to antibacterial benefits and healthier tank conditions.

Encourages Better Colour & Breeding Behaviour – Many hobbyists use botanicals like these to promote improved coloration and spawning behaviour in softwater species.

✅ Best For
Shrimp (low pH shrimp setups) | Betta | Tetras | Discus | Softwater fish | Blackwater aquascape | Biotope tanks

✅ How To Use ✅
|Step 1: Quick rinse with clean water (remove dust)
Step 2: Add directly into tank OR pre-soak to help it sink faster
Step 3: Start with small amount, monitor pH and water colour, then adjust as needed (every tank differs)

📌 Note: Tannins may tint water slightly yellow/brown (normal blackwater effect). Use activated carbon if you prefer clearer water.

📦 What You Receive 📦
1 pack ANS Casuarina Cones (natural cones)

Q1: What do Casuarina cones do in an aquarium?
A: They release tannins and humic substances that help create blackwater conditions and can gently reduce pH, making the environment more natural for shrimp and softwater fish.

Q2: Will it turn my water brown/yellow?
A: Yes, a light tea tint is normal because of tannins. This is the “blackwater” look many hobbyists want. If you don’t like it, use carbon or do water changes.

Q3: How many cones should I use?
A: Start small and adjust. Some hobbyists use around 5–6 cones per 10 gallons, but results vary by tank size and water parameters, so monitor pH.

Q4: Is it good for shrimp babies?
A: Yes. The cones provide small hiding areas, and biofilm grows on the surface which becomes natural grazing food for baby shrimp.
