Aquarium Water – Liquid Gold for Your Garden
It offers a natural source of burn free nitrogen, plus other primary nutrients like phosphorus and potassium. Unlike synthetic fertilizers, fish fertilizers may also provide secondary nutrients such as calcium. Plants that get a balance of both primary and secondary nutrients experience strong and steady growth which results to stronger plants that can better stand issues related to pest and diseases.
Dried Fish Fertilizer Concentrate contains a natural N-P-K (Nitrogen-Phosphorus-Potash) level of 11-5-1. Unlike the liquid fish emulsion that is preserved with high levels of acid, dried fish powder has no danger of burning the plants roots.
Nitrogen is the primary reason. Another nutrient that plants need in abundance (though not usually as much as nitrogen) is phosphorous, and aquarium water typically has a fairly high concentration of this as well as these materials are common bi-products of a fish’s metabolism and are brought into the aquarium in the food you give your fish.
Potassium is another nutrient required by plants, and while aquarium water is not typically very high in potassium, it is usually at least as abundant as in regular tap water.
Other micronutrients may also be present and beneficial to plants, such as iron and magnesium.
But another reason which is often overlooked is the presence of beneficial bacteria in aquarium water. These bacteria are always present in a healthy aquarium, and when used to water plants, the bacteria can help make nutrients which are already present in the soil more useful to the plants by breaking them down into a form which is more bioavailable, or more easily absorbed by the plant’s roots and utilized by the plant for growth.
