... great value for the money! beautiful colors increase the value for me! the small size of these tiny rocks make my use for them a perfect fit (see pic). can increase the enjoyment of aquariums ponds crafts and rooting plants by the visually enhanced appealing colors that create a peaceful feeling just looking at it daily. can't beat the price locally and the delivery time was next day for me. top notch all around! ...

nice colors:

I like the name of the aquarium gravel, I always rinse my gravel before putting it in the aquarium we had a ten gallon tank we put five bags in the aquarium to have a lot of extra gravel to make it pretty.
