Also posted this under Catchment pH issues. We have a large freshwater/brackish pond in Hilo, which has Ceratophyllum (hornswort?) algae, the type you find in fishtanks, it's a good organic fertilizer, high in nitrogen. If you would like to try the algae on your plants or in the garden, you more than welcome to come and get some, it's FREE!
