According to the packaging the gravel should be washed warm.
Handful I promptly do without this scattered into the basin and may notice a certain opacity in the bedding site.
The rest of the gravel, I then washed of course and thus prevent clouding of the aquarium water mostly.
To help me stand the bathtub, a retired noodle eggs and an absolutely terrible T-Shirt ;-)
Gravel I have given in several stages in the designed with the T-shirt as a filter noodle eggs.
Good abgebraust and durchmengt manually could take the T-shirt like a sack carrying the aquarium and let the gravel easily trickling. In this process I feel the noticed particularly positive.
For an area of 120x50 three bags gravel have been enough for me.
In addition to appearance and feel is supported by the substance of the product.
In another bowl, I use JBL Manado and quartz sand.
Each of these reasons floor has its place, but it should be noted in quartz sand, that he is troubled by quickly like to tarnish something (depending on trim) and the water.
In Manado, however, I found the dust (the fill / wash) by transport-related wear something ugly.
Conclusion:
Definitely a buy recommendation!
