The Original BioPellets 500ml

DVH The Original BioPellets is a biological nutrient-removal medium for marine aquarium owners dealing with elevated NO₃ and PO₄. Instead of daily dosing of chemical products, the pellets are placed in a filter chamber where bacteria colonise them and consume nitrates and phosphates.

Why it matters

• Biodegradable carbon source: the pellets are made of biodegradable polymers, and bacteria settle and multiply on them, converting NO₃ and PO₄ into biomass.
• Excess bacterial biomass enters the aquarium circulation as food for corals and other organisms, while the remainder is removed by the protein skimmer.
• Bacteria grow inside the filter chamber, not throughout the whole aquarium volume.
• Long service interval: pellets are gradually consumed, so top-ups are needed only every 3–6 months.

Specifications

• Brand / model: DVH The Original BioPellets 500 ml (symbol DVH BIOPELLETS ORIGINAL 500ML)
• EAN: 094922675002
• Weight: 0.5 kg
• Dosing: 50–200 ml per 100 l of water
• Bacterial activation time: 2–6 weeks, depending on the system
• Top-up interval: every 3–6 months, when the pellet volume decreases
• Recommended NO₃:PO₄ ratio: 1:0.01
• High NO₃ (above 20 ppm): introduce the pellets gradually

What it works with

The product is designed for marine aquariums and is applied in fluidised or recirculating filter systems, where the pellets can be placed in the filter chamber. Dosing is scaled to the water volume at 50–200 ml per 100 l, so the amount should be matched to the tank size and the current nutrient levels. It works alongside existing filtration and a protein skimmer, which removes surplus bacterial biomass.
