Glow Gravel for Fish Tanks
Glow in the Dark Gravel
What is it?
When exposed to almost any artificial or natural light source, the glow particles will absorb the light energy and store it. When it starts to get darker, the light energy will be released as a glow.Buy Now
We use premium quality strontium aluminate as the glow in the dark element in our stones. Other products on the market use zinc sulphide which has a much lower glow time and brightness, and is also cheaper.
The concentration of powder is high, resulting in more particles that glow in every rock and no fillers.
It only takes minutes to charge by any light and and they'll glow for around 10 hours, initially very strong then slowly reducing as the night goes on.Our resin blend gives our rocks a realistic marble appearance, rather than plastic or glass.
How safe are they?
No chemical reactions take place for the pebbles to glow. This is a passive process of absorption and release of light energy.
The glow stones are non-toxic so absolutely fine around animals and fish.Buy Now
Each bag of gravel contains 300g of mixed river pebble and 3 colours of glow pebble.
There is a slight natural variation in the size of each glow stone, but on average they are around 8-15mm.
