Left: the original NP BioPellets Right: The mistakenly high lipid content pellet
NP BioPellets is offering free product replacements for customers who have mistakenly received a different biopellet version that contains an increased “lipids”. These fatty acids are shutting down skimmers for aquarists that have used them–a potentially serious issue when biomass export is required to reduce nitrate and phosphate that has been assimilated by bacteria grown on the carbon source substrate.

A mixture of good and ‘bad’ biopellets in 500ml packaging.
DVH Import has stated skimming should resume in 2-3 days, but for those seeking the original pellet design they can receive a replacement pack free charge. For now, users who have received the square shaped pellets are urged to remove them, and only utilize the original oval shaped NP Biopellet [See their full customer letter below; emphasis our own]
Note: North American distributor Aquarium Specialty has said that no N.A. based customers have received these pellets and all packages have been examined prior to sale. We suggest all users, especially those in Europe & Hong Kong where these bad batches have been seen, “verify their pellets”.

Dear Customers,
We got some news from the users who are using our NP Reducing BioPellets. The problem is that the skimmer stops skimming when people add the NP Reducing BioPellets. We checked our control batch, which we keep from each incomming shipment, at our warehouse and found a odd shaped BioPellet in a 300KG bulk batch.
These odd shaped pellets (see picture) is a NP Reducing BioPellet but it came from a other production machine at our manufacturer. They do work, but it takes longer before they start working. Next to that they contain more lipids then normaly. This is why the skimmer stops functioning. Depending on the used volume of the BioPellets most of the skimmers start working again in 2-3 days. In some cases it takes (much) longer. These odd shaped pellets are not harmfull for your animals.
What to do:
If your skimmer stops working when you have added the NP Reducing BioPellets and you have 2 shapes of NP Reducing BioPellets, contact the store where you bought the NP Reducing BioPellets for more information to solve this problem. What you can do in the mean time: 1.) Take out the NP Reducing BioPellets till you contacted the store and helped you solve the problem or 2.) Sort out the 2 shapes of BioPellets and put only with oval shaped pellets back in to the system, not the square ones. Do contact the store where you bought the NP Reducing BioPellets. We will compensate all customers who got the 2 different pellets and have problems with the skimmer by shipping replacement bags to the local distributors ASAP.
We apologies for all the trouble. We are doing our best to make all customer happy again with our NP Reducing BioPellets.
We want to point out that there are no fake BioPellets on the market as is suggested by some. All our newly shipped NP Reducing BioPellets are thermo sealed.
Sincerely yours,
Dennis van Houten
Director D. van Houten (Import – Export – Euro*Depot/Distribution) exporter NP Reducing BioPellets
