I have been setting up a 55 gallon tank for the past 3 months to be a stream-like tank hopefully with some native fish from New Mexico (if I can find any). For circulation I added two powerheads which are connected to 1" PVC tubing that travels under the substrate to the other side of the tank. The intake for a Cascade 1000 Canister Filter is also on the same side as the intake as the power heads. The sand is from the Rio Grande, large rocks from the front yard, small rocks are from Home Depot, and the wood is Malaysian Driftwood from DFS. Thanks for looking.
