Designed for excellent performance and easy maintenance, Botanicare’s Premium Reservoirs are exceptionally durable, and are true gallon capacity plus extra room for aeration. They include front and back bulkhead access ports to accommodate pump lines and allow multiple reservoirs to be joined in line or side-by-side. Made from BPA-free materials, virgin, UV light-resistant ABS plastic wraps the 70 percent recycled core. Each reservoir lid includes a built in access port which eliminates the need to remove the lid when adding nutrients. These Premium Reservoirs are made in the USA using renewable solar energy and include a one-year warranty. The 115-gallon Premium Reservoir measures 83 inches x 35 inches x 13.5 inches.
