Our valve manifolds will save you time and aggravation. They are made with quarter-turn ball valves. The manifold ports are 1/2" FNPT and a 1/2" FNPT plug is included.
Each valve is 1/4" FNPT. Each valve will pass .5 gpm with less than 1 psi pressure loss. They also make excellent manifolds for air distribution. The 1/2" threaded plug may be removed for another connection.
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.
