Most instructions will tell you to fill up the tub or liner-created basin with large gravel. This works, but I find that if you use short sections of corrugated drain tile, you will have more space for water to store (the reservoir). The idea is to have enough water stored so that you won't have to worry about filling the reservoir all the time, as rain will usually replenish it safely. Using all gravel leaves only about 20% of the space for water. This "opens up" lots of room for water. I've seen special crates sold at pond centers for this purpose, but they cost over $20 each! For a few dollars, you can accomplish the same thing. (After the next step, I will be using some gravel.)
