Aquarium Advice Freak
I'm new to aquarium forums, but only rusty to the hobby. I LOVE that aquariumadvice has a DYI section. I had to go back through some old picture cause I wanted to add this. I wanted some retaining walls to hold back deeper sections of gravel for better planting. Plus I like the different levels at the bottom of the tank. The commercial ones are about $20 each and generally only about 2 maybe 3 inches high. I know a little about various rocks, enough to know that not all rocks are suitable inside an aquarium. Anyway, you can buy a large bag of pond pebbles at Home Depot for $3-$4 (wash it thoroughly) then get aquarium safe silicone $3-$4. You'll need a little patience since it's like putting a horrible puzzle together and there are moments you'll have to let it sit for an hour to let the silicone set up a bit before adding more rock. Also, make sure you don't use any rocks with sharp edges.
