Want a quick and inexpensive sump for your aquarium? How about a shallow water frag tank, or just an open area to grow red mangroves? In all of those situations, Rubbermaid has a product for you. They offer a heavy duty stock tank (aka horse trough) that comes in many different sizes, though all are typically quite large. These tanks are very durable and are completely safe to use on your aquarium. Just plumb it in line with your aquarium and use it as a huge sump area to house aquarium equipment or grow macroalgae. If you’re an established hobbyitsts that’s looking to relocate, the troughs really come in handy as a temporary holding container.
