Die Einrichtung besteht aus Seiryu Steinen und täuschend echt aussehenden Deko-Kunstpflanzen (nicht die speziell für Aquarien hergestellten), alles fest montiert auf einer Plexiglas-Bodenplatte abgedeckt mit feinen Basaltsplitt.Das Wasser ist dank eines UVC-Filters kristallklar. Nitrit- und Nitratwerte waren mit den JBL-Tests kaum nachweisbar, Silikat und Phosphat aber deutlich erhöht. Das Brackwasser stelle ich aus destilliertem Wasser und synthetischem, silikat-, phosphat- und nitratfreien Meersalz her. Woher die stark erhöhten Silikat und Phosphatwerte im Wasser herrührten, kann ich nicht genau sagen. Ich vermute, dass das Silikat vom verwendeten Basaltsplit und die Phosphate vom Garnelenfutter herrührten.Nachdem ich Seachem PhosNet Synthetic GFO in einen feinmaschigen Ansaugkorb (Filter Guard 17mm, beidseitig mit End-Kappen verschlossen) gefüllt und in den 1-Liter-Eigenbau-Aussenfilter mit UVC-Strahler gelegt habe, ist das Wasser nun dauerhaft phosphat- und silikatfrei. Die Algen waren waren schon nach realtiv kurzer Zeit verschwunden. Für mich ist Seachem PhosNet Synthetic GFO eine klare Kaufempfehlung. ### ⭐⭐⭐ Picture does not match product *by S***N on Reviewed in Canada on 20 September 2020* Judging from the picture I was expecting a tub of Granular Ferric Oxide. What I got was a little baggie package with a small bag full of Granular Ferric Oxide. Very misleading photo.Three stars because the description was on point, was the same weight, and is the same product. Two stars down for the photos. ### ⭐⭐⭐⭐⭐ Works *by A***E on Reviewed in Canada on 22 July 2018* Works well. My phosphates were super high and I had a crazy alge outbreak. Have been using as per the instructions and phosphates are coming down and alge is starting get under control. --- ## 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.co.za/products/78211915-seachem-phosnet-phosphate-silicate-remover-aquarium-filter-media-250g-8](https://www.desertcart.co.za/products/78211915-seachem-phosnet-phosphate-silicate-remover-aquarium-filter-media-250g-8) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-31*
