Product Information
Full details
NT Labs Barley Straw Pouches are an ideal choice for pond owners seeking a natural, non-toxic method to manage green water algae and blanketweed. By slowly releasing organic compounds over a 28-day decomposition cycle, these pouches help clarify pond water without posing risks to fish, plants, or wildlife. While this is a highly effective preventative maintenance tool, users should note that it acts as a gradual biological treatment rather than an instant chemical fix for severe infestations.

FAQs
Are these safe for my koi and lilies?
Yes, the pouches are entirely non-toxic and will not harm fish, lilies, or any other aquatic plants.
How often do I need to replace the pouch?
For optimal effectiveness, you should replace the pouch every 28 days as it decomposes.
Can I use this in a wildlife pond?
Absolutely. It is safe for all pets, birds, and frogs that may visit or live in your pond.
Will it work if my pond is larger than 800 gallons?
Yes, simply scale the number of pouches according to your total volume (e.g., two pouches for 1,600 gallons).
Does it expire?
Stored in a cool, dry place, the pouches have a long shelf life. However, once placed in water, the active lifespan is approximately 28 days.
Troubleshooting
Water is not clearing after 14 days
Check that the pouch is located in an area with good water flow. If the pond is heavily overstocked with fish or receives excessive direct sunlight, you may need to increase the number of pouches used.
Blanketweed is still growing
Barley straw inhibits new growth. Manually remove existing, established blanketweed with a net or rake to allow the pouch to prevent further spread.
Pros and Cons
Pros
- 100% natural and chemical-free
- Completely safe for sensitive pond ecosystems
- Easy to drop into the pond or filtration system
- Effective against both blanketweed and suspended green water
Cons
- Not a fast-acting solution for immediate clear-up
- Requires regular replacement every 28 days for continuous results
- Performance is dependent on water temperature and flow
Setup, Compatibility & Care
To set up your pouch, simply submerge it directly into your pond at a depth where it can be easily retrieved. If you have a biological filter, placing the pouch inside the filter box or bay can increase the concentration of the treatment, though it should be kept away from delicate impellers.
Compatibility is universal; because the product is non-toxic, it can be used alongside traditional filtration systems and other water treatments without negative interactions. For maintenance, replace the pouches every 28 days to maintain the necessary concentration of active factors. Discard the used, decomposed straw in your garden compost bin, as it is a fully biodegradable organic material.
