Pond Boss Forums MANAGING AN EXISTING POND Fertilization Pelletized Lime. As effective as powdered?

Mark A.-most likely you need lime, especially if soil is sandy and you are surrounded by pine trees. Test the water as Greg suggests, the county agent has a form, and it costs $20. Now is the time to lime. The amount to apply is based on your alkalinity reading, and amount of water flow through your pond.
Aglime is cornmeal size grains of calcium carbonate. Be wary of pelletized lime..it is likely calcium hydroxide, not aglime. You want calcium carbonate. Most recommendations for east Texas are one ton per surface acre. But, it's not too expensive, and with lots of flow through, it makes sense to add more than that.
