With the lowest leachable phosphate content and minimal ash, it maintains stable pH levels while removing organic waste twice as effectively as standard carbons. Ideal for professional aquarists seeking long-lasting, high-performance filtration media. ## Description MatrixCarbon™ is a truly unique activated carbon. It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. MatrixCarbon™ has a very low ash content as indicated by its minimal impact on pH. Even when added to distilled water, it does not raise pH above 7.0. While all carbons contain phosphate, regardless of false claims to the contrary, MatrixCarbon™ has the lowest detectable leachable phosphate content of all major carbon brands tested. MatrixCarbon™ outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use. While carbon is generally considered to be a chemical filter, that is not precisely true. It is in fact a mechanical filter as well, but it is only capable of mechanically filtering objects of molecular size. It functions through extremely small cracks and crevices, called macropores and micropores. Microporous carbons remove primarily metals and smaller ions (like trace minerals) and are best suited to air filtration, while macroporous carbons remove primarily larger organic molecules (like nitrogenous waste) and are best suited to water filtration. The ingredients from which a carbon is manufactured determine whether it will be macro- or microporous. Carbons made from coconut shell and other organic products form microporous carbons, while carbons made from bituminous coal form macroporous carbons. MatrixCarbon™ is a bituminous coal-based, macroporous carbon. It is the only spherical carbon on the market, allowing for maximum water flow. It is sized to allow full penetration by water, but not small enough to escape filter bags. All carbons contain phosphate. However, that phosphate DOES NOT come from washing the carbon with phosphoric acid. Most carbons are washed with sulfuric acid. The phosphate is contained in the ash from the carbon source. The main purpose of acid-washing is to remove ash. Because of MatrixCarbon’s™ hydrodynamic properties, more ash is washed from our carbon than any other. Therefore, it has the lowest leachable phosphate on the market.

I don't use carbon. ## Customer Reviews ### ⭐⭐⭐⭐ All good but watch ph decrease *by B***Y on 27 October 2025* ### ⭐⭐⭐⭐⭐ Excellent product *by D***. on 16 October 2025* ### ⭐⭐⭐⭐⭐ Very convenient! *by M***E on 27 December 2024* ## Frequently Bought Together - Tidal Filter 35 Matrix Carbon 90 ml - Seachem Tidal 35 Filter Replacement Foam (2 Pack), Blue - Seachem Tidal Power Aquarium Filter - 35 Gallon Large Fish Tank Filter,black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/388976732-seachem-tidal-filter-35-matrix-carbon-90-ml](https://www.desertcart.dk/products/388976732-seachem-tidal-filter-35-matrix-carbon-90-ml) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-22*
