Kolar LabsMetabolix Bio-Pellets – Nitrate & Phosphate Treatment for All Aquariums, Fresh & Salt Water, 600g, 1.32 lb

This is already reducing my nutrients. The price is right and I'll keep ordering more since I have 400 gallons to treat.

Wow! It Works I finally reduce Ammonia in my marine aquarium it took 50 years to do it until I found this produce I was trying to find a way to reduce Ammonia without a sump this product did it. I only had HOB hang on back filter two Emperor and Aqua Clear is was not enough Bio filtration. Untill I tired with product with the Bio Reactor from two little fishes.

I added these Kolar bio-pellets to my "AQQA Aquarium Fluidized Moving Bed Filter". They work very well together.

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.

This product must be introduced slowly but prevents algae growth and using chemicals to control Phosphates.

Received item fast delivered thank you

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.

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!
