    Best GFO I have ever used. The particle size is larger than other competitors products which greatly reduces the chance of blockage, reduced flow or channeling which is common when using phosphate removers in reactors. First time I’ve been able to exhaust a GFO before a blockage occurred. Really impressed and will only buy this from now on. Works great at removing phosphates.

    Petite quantité, mais efficace. Par contre pour grand aquarium avec pas mal de PO4, insuffisant.

    Calidad precio. Perfecto

    Cantidad y calidad, nada que envidiar a los productos de otras marcas, top. Funciona de manera progresiva, no es un producto milagro, si tienes condensaciones superiores, a 0,5 tarda más y recomiendo cambios de agua y sifonar. Además este producto combinado con fhos out 4, de la misma marca son top, para la limpieza de fosfatos en cuestión de 48 a 72 horas.

    Bien que souvent décrit comme illusoire, la baisse est néanmoins réelle, mais assez lente, il faudra renouveler souvent le produit. Sur un bac en cyclage (po4 provenant des pierres) ça fait très bien le travail.
