- They lower the pH of water naturally
- Inhibit many types of bacteria and fungus
- Stimulates breeding in Bettas
- Conditions Betta scales and fins to improve their health
- And provides natural hiding spots for additional security
Nutritional Benefits
Natural leaf litter is the #1 source of biofilm for aquariums. These leaves decay over a long period, contributing to a stable and healthy aquatic environment.

I’ve used NewCal Banana Bark in my Betta tank for three months. The water clarity improved and my Betta has started breeding. The leaves break down slowly and create a natural hiding spot. No fish have shown signs of illness.

The bark helps maintain stable pH and keeps the tank clean. I noticed fewer algae blooms and the fish seem more active. It’s a simple addition that makes a big difference.

After switching from synthetic substrates, my Betta’s fins look healthier. The natural decay process supports good bacteria growth. I love the peace of mind knowing the tank is more balanced.

It’s effective for pH control and provides hiding spots. The leaves take time to break down, so it’s a long-term investment. Works well with my existing filter setup.
