Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 Lbs

Used Flourite to replace 66% of the gravel in my 200l aquarium while the fish were in it. Washed the Flourite in colander till water was clear. 1) Removed plants and vacuumed old gravel. 2) Took out the gravel where the plants were (fish loved it, kept getting in the way, especially the guppies) this did cause murkiness. 3) Waited an hour for murkiness to subside, added the Flourite and it definitely did not add to murkiness. 4) Filled aquarium, ran filter for two hours, water quite clear. 5) Switch of filters, replace plants. 6) Switch on filters (2 internal canister filters and under gravel filter with 3 200l/h power heads). Two hours later water 90% clear, by morning glass clear. I also used the same batch of Flourite for a new 50l nano tank, zero murkiness. Have had aquariums for 30 years, used many gravels that I always pre-washed, so I can confidently state that the Flourite after washing is among the cleanest substrates. Fish all alive and well and plants definitely happier than in my old plain gravel.

very cloudy at first , need to be washed 5-6 times once added to aquarium and using filter , it will settle down fast Plants are growing very fast bit expensive

Easy to rinse and use for plants

I ordered 2 bag ( the sand comes with definite cooler )

Easy to install just rinse let settle .

Produtos da marca seachem, vc pode comprar de olho fechado, pois até o momento, não conheço nenhum que seja ruim. Utilizo vários produtos da seachem, como ração clorella flakers, purigen, seagel, acid buffer, alkaline buffer, prime, stability, flourish e stress guard, todos muito bons e agora o substrato flourith black.

Great inert substrate if you don’t want to alter your water chemistry by using substrates like aqua soil etc. Can’t speak to its utility for planted tanks as I’m using it in a sparsely planted shrimp breeding tank. Incredibly dusty so be sure to rinse thoroughly before adding it to aquarium. Rinse in a bucket until water runs clear and be careful when filling aquarium not to disturb it.

Bought this for my new 75gal tank that will be planted. I love it, it looks amazing and most of the reviews complained about it leaving a thick grey film or really cloudy water well it says right on the bags to rinse it, so that what I did, I used an old wash tub with a window screen over it and a medium sized colander. I did one bag at a time, poured it into the colander and rinsed it with a low flow of water, mixing it until the water ran mostly clear. Put it in my tank and the water was a little cloudy but 24 hours later with my filter running the water is crystal clear. I would definitely buy this again for another aquarium.

Arrivato in tempo, molto polveroso bisogna sciacquare
