Sand in silicone reef tank

[starrynight99]

I’ve been noticing some sand grains in the silicone of my reef tank. The tank is 1000 litres and built only 9 months ago.

Is this of concerns? I have not noticed any worms and don’t think I’ve been scraping the sand too close to the silicone. Thanks for any input.

Would you better describe your system.

When you say sand in silicone, does silicone mean the seal gluing bottom glass to front glass?
