Pro Carbon 4 000 ml — Bulk Low-Phosphate Reef Activated Carbon - Polyplab

Polyplab Pro Carbon 4 000 ml — reef activated carbon in a bulk size

Polyplab Pro Carbon 4,000 ml is the large format of the high-performance activated carbon that delivers crystal-clear water in marine and freshwater aquariums alike. Manufactured under strict quality controls, this 4 L size suits large reef tanks or use over several months.

What Pro Carbon removes

Pro Carbon quickly improves water quality by adsorbing harmful toxins, impurities, organic wastes, medication residues and more. It's also what clears yellowing and brings the water back to full clarity.

The low-phosphate advantage

Impure carbons can leach phosphate — their POI can climb as high as 14 — feeding nuisance algae and slowing hard-coral growth. Pro Carbon has one of the lowest POI levels in the industry: only 1.3. Less phosphate leached means less algae risk.

Specifications

• Size: 4,000 ml (4 L, bulk size)
• High-performance activated carbon, highly active
• pH balanced
• Pellet form to reduce dust and fine grains
• One of the lowest phosphate levels in the industry (POI 1.3)

Directions (per Polyplab)

• Rinse Pro Carbon with clean water before use to remove carbon dust.
• Place it between layers of fine filter media, in an area of the sump with strong flow.
• It's also perfect for use in a media reactor.
• Polyplab doesn't publish a precise ml/gallon ratio: match the amount to your system volume and replace when performance drops (less clarity, yellowing returns).

Good to know

Activated carbon also adsorbs the amino acids and supplements you dose. If you're using Colors, RF Acides or RF Fuel, avoid running Pro Carbon continuously — many reefers run it a few days at a time rather than full-time.

FAQ

How do I use Polyplab Pro Carbon 4 000 ml?

Rinse it with clean water, then place it between layers of fine media in a high-flow area of the sump, or in a media reactor. Polyplab doesn't publish a precise ml/gallon dose.

Why choose a low-phosphate carbon?

An impure carbon can leach phosphate (POI up to 14) and feed algae. Pro Carbon has a POI of just 1.3, among the lowest in the industry.

Who is the 4 L size for?

For large systems or reefers who change carbon often: it's the most economical format, the same formula as the 1,000 ml in a larger quantity.
