Spectrastone 40507 First Impressions
Bright color.
The gravel size is exactly as described in the product description- 2 to 4mm. If you have to bury tank decor that doesn't have suction cups then you need more. Really just rinsed a little and ready to go. They are rocks, what more do you need. I bought two bags for my 55 gallon. I rinsed it before I put it in the tank. Like everyone else says wash it before putting it in your tank.

Spectrastone 40507 Final Thoughts
Love these!
I planned on spending 24-48 hours removing all the dust in washes and soaks. Removed pebbles and refilled for the 3rd time. 5 inches of gravel, so you could use more or less depending on tank size. So far, really happy with how it looks in my small tank. A little bigger than what I wanted but I still used it. I absolutely love how the rocks glow in my tank! I envisioned the bag being bigger since I ordered a 50lbs.
