Kent Freshwater Plant Supplement provides essential trace minerals for lush growth of freshwater plants. Our goal is to provide Sustained Long-term Results. To this end, Freshwater Plant Supplement contains no fertilizers which tend to encourage unwanted algae growth. The iron used in Freshwater Plant Supplement is iron EDTA. It is as strong or stonger than any plant supplement or fertilizer on the market. It is yellow in color, and is the most expensive iron available. It will take the place of tropical laterite, and is easier to use. Unlike other dark brown irons, it will stay in solution longer and provide sustained iron to plants over a long period of time. Do not be fooled by the lightness of the color and do not overdose your system because of the color. Do not use more than twice the recommended dosage. You may also want to use new Kent Blackwater Expert which will provide superb spawning conditions for your fish, as well as spuring plant growth!.Plants also require strong lighting of proper spectrum and abundant carbon dioxide in the system. If you are planning a heavily planted tank, you may want to invest in a CO2 system. Metal Halide lights are excellent plant lights if you are really serious about a beautiful plant tank. In new aquariums or those with few or no fish, plants may need some additional nitrates and phosphates. If so, use a fertilizer in combination with Freshwater Plant Supplement, but be careful, as you can easily have an algae farm!.Freshwater Plant Supplement can be used simultaneously with all Kent freshwater products including Freshwater Trace Elements, Discus Trace Elements or A F Cichlid Rift Lake Trace Elements.
