Quartz gravel

Very nice dark colored substrate as I wanted it. Bags received intact.

Superb black gravel (rather dark gray once in the aquarium) not sharp, very clean so 1 or 2 rinses in a bucket are enough. The grain size and shape really do not hurt the groundfish while ensuring good water circulation.

Beautiful gravel, but one of the two bags was disemboweled, fortunately without too much loss ...

Super product I have in 3 of my aquariums and it has an extra rendering! only downside are high price ... But hey I have a lot of bottom species (corrydoras, shrimps, khuli, otocynclus) and no problem. It is clean but I still recommend to rinse it before use, but pro quality product for a pro!

I ordered 4 bags for my 270L it's perfect! It is very dark exactly what I wanted. Qualität Dennerle, I washed the quartz anyway one shot before putting it in the tank! Do not hesitate

Ideal gravel for plants (grains neither too big nor too small) and burrowing fish (do not cut). And I find the color top. Ordered Monday evening, arrived on Wednesday morning.
