Two Little Fishies NPX Bioplastics Biopellets
Two Little Fishies NPX Bioplastics are solid biopellets that naturally lower nitrate and phosphate in your reef aquarium. Tumbled in a media reactor, they feed beneficial bacteria that consume excess nutrients, giving you cleaner water, better color, and less algae. Pair them with your corals for a healthier reef.
Why NPX Bioplastics
- Reduces both nitrate and phosphate at the same time
- Feeds nutrient-consuming bacteria as they tumble
- Leads to cleaner water, better color, and less algae
- A proven carbon-dosing method in solid form
- Long-lasting, top off as the pellets are consumed
How to Use
- Run the pellets in a fluidized media reactor with moderate tumbling
- Start with a smaller amount and increase gradually over weeks
- Feed the reactor output near your protein skimmer intake
- Top off with new pellets as the volume slowly drops

Frequently Asked Questions
How do biopellets work?
They are a solid carbon source that grows bacteria to consume nitrate and phosphate as they tumble in a reactor, then the bacteria are exported by your skimmer.
Do I need a reactor?
Yes, biopellets work best fluidized in a media reactor with moderate tumbling.
How much do I use?
Start with less than the maximum for your tank size and increase gradually so your tank adjusts.
