These PVC globe valves are glued together as manifolds to save time. Each valve will pass 2 gpm with less than 1 psi pressure loss. The valves have 1/2" FPT outlets. The manifold ports are 1/2" FPT and a threaded plug is included. Made in USA.
You should stop feeding your aquatic plants about a month before the first frost in your area. Even in areas that don't normally have frost, plant growth slows in the shorter, cooler days of the fall and winter months.
