The Original BioPellets 250ml

DVH The Original BioPellets is a media for marine reef aquarists dealing with excess nitrate and phosphate, which drive algae growth and destabilise water parameters. The pellets are placed in a fluidized or recirculating filter, where they serve as the feed base for nutrient-consuming bacteria, so no daily dosing of additives is needed.

Why it matters

• Biodegradable polymer base: the pellets provide organic carbon, and bacteria colonise them and convert NO₃ and PO₄ into biomass.
• Growth confined to the filter chamber: the bacterial population develops in the filtration compartment rather than throughout the display tank.
• Surplus biomass used in the system: excess bacteria enter the aquarium as food for corals and other organisms, while the remainder is removed by the protein skimmer.
• Long service interval: the pellets are consumed gradually and need topping up only every 3–6 months.

Specifications

• Weight: 0.25 kg
• Dosing: 50–200 ml per 100 l of water
• Bacterial activation time: 2–6 weeks, depending on the system
• Recommended NO₃:PO₄ ratio: 1:0.01
• Gradual introduction required when NO₃ exceeds 20 ppm

What it works with

The product is designed for marine aquariums with a reef or coral focus, run on a fluidized or recirculating filter. Dosing scales with water volume at 50–200 ml per 100 l, so the quantity should be matched to the tank size and current nutrient levels. Because the bacteria are fed by the pellets and their surplus is removed by a skimmer, it pairs with a protein skimmer in the system.
