## Description

Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 Lbs : desertcart.ae: Pet Supplies

Review: Clean and Green - 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.
Review: Good substrate - a bit expensive - 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
