I believe we have a substrate calculator that will help you determine how much Aqua Soil you will need for your 29G.
What are you planning to layer the Aqua Soil with? Like we said earlier, layering with something finer grained is going to lead to the finer grained substrate working it's way under the Aqua Soil. A bigger grained substrate is going to work it's way over the Aqua Soil. That is why a person using Aqua Soil and Power Sand needs to be very careful about how it is layered and how much of each product is used.
Mixing Aqua Soil with another is kind of pointless. It is a great stand alone substrate. There is no other substrate you can add to Aqua Soil that is going to make it a better product as far as I know.
