I actually added the substrate before the water, but since my camera was down I wasn't able to take pictures until after I had added the water. So for continuity's sake, I am posting the pictures of the finished substrate now. The strainer helped create an even sized substrate that looks quite nice. I am happy with the appearance of the results. I am excited to see what benefits the Flourite will bring to the growth of the plants that will be living in this aquarium.
One of the most exciting things for me is the rock while sitting on the gravel. It sits very securely and provides ledges around the corners. I have dug some of the gravel out from under these ledges and created a couple of small caves. It's a little difficult to see in pictures above and below this paragraph, but there are four areas of shelter created by the rock. This is wonderful, because a fish that has plenty of places to hide is much less likely to do so. The neatest cave is the one in the back right corner. It's so large that I can stick my four fingers into it all the way up to the knuckles. It definitely provides the most security, as the entrance to the cave is facing the black background.
I'm happy with my substrate choice up to this point. I read all sorts of warnings about the tank becoming forever cloudy if the substrate isn't rinsed well enough. I must have done a good job, because I haven't notice any cloudiness in the water even when I disturb the substrate. No problems here.
