Back to Nature Sinking River Stone, B (25x21x9cm)

River Stones – clear for diving! With the River Stones, Back to Nature has created the first self-sinking BtN aquarium rocks.

River stones are characteristically rounded and smoothened by the current, and we have used this form to inspire the shape of our River Stones. The sinking stones from Back to Nature are hand-made in Europe and they are based on real-world models. Their structure and colors are ideal for the creation of nature aquariums or for use in a planted tank. Here you can set beautiful accents with these stones but don't have to accept the negative effects some stones can have on your water quality.

The River Stones do not influence your water parameters at all and can therefore also be used in aquariums with very soft water. This type of aquarium is unsuitable for many nice natural stones since they would give off lime to the water and therefore harden it unduly.

Our expert Oliver Knott says:
The River Stones from Back to Nature are absolutely safe for all aquarium animals and even withstand the activities of intensely rasping aquarium pets like catfish, for example.
