Description

Improve the Quality of Your Aquarium Kolar Labs Metabolix Bio-Pellets are a pure, natural way to keep and create a healthier aquarium environment for your fish and plant life. The PHA pearls slowly dissolve leading to a reduction in nitrate and phosphate levels in your aquarium water. Made without fillers or harmful chemicals, our 100% PHA Bio-Pellets are safe for all fish and corals across all types of water and aquariums. For best results, we recommend using with a fluidized media reactor with gentle tumbling of the media in water flow. Kolar Labs Metabolix Bio-Pellets are made to rigorous quality and purity standards in the USA. How to Use: ● Standard dose – 180g or approximately 1 cup/50 gallons in a fluidized reactor ● For aquariums with measurable nitrates – ½ to even ¼ starting dose for the first 3-4 weeks, increasing weekly thereafter ● Add or replace pellets as needed – do not let pellets dissolve below ½ the original amount ● Rinse and soak new media for up to 24 hours to prevent floating ● Keep pellets moving within reactor to prevent clumping or clogging ● For best results, exiting water from fluidized reactor should flow directly into a quality protein skimmer intake ● Watch for cloudiness during the first 4 weeks – if substantial cloudiness occurs, reduce pellets by ½ and change water Get to Know Kolar Labs Kolar Labs has been the source for premium filter medias in the aquarium industry for years.

  • adjust your reactor flow to stop clumping.
Size: 10.58 Ounce (Pack of 1)
does not tumble as well and clumps more than the Dr. Tims , i will be switching back to that. and for people who say bio media dont work keep in mind it may take several months to get seeded and start reducing Nitrate.

Works well in my reactor, rearing very expensive L# pleco fry and wanted some margin of error so I could feed adequately for growth. Nitrates kept a near zero with frequent water changes regardless but this was cheap peace of mind.

  • Reduces nitrate as advertised.

Exactly as advertised. Good way of reducing nitrate slowly. I had mine is a media reactor with slow flow and just a little tumbling. Start slow!
