Laguna Fertilizer Pond Spikes supply important nutrition to aquatic plants for a period of one year. The temperature-activated feeding sticks release nutrients only when plants need them most - at or above 50 degrees Fahrenheit. Once activated, the spikes slowly release a well-balanced feeding formula that maximizes the size and color all aquatic plants. With low amounts of phosphorous and zero copper, the pond spikes have no adverse effect on water quality and are non-toxic to fish and plant life. Laguna Fertilizer Pond Spikes are specifically designed for potted plants and are compatible with all planting baskets.
