Amazon Sword is a very popular plant within the aquarium hobby due to its great appearance and easy availability. It requires fine, iron-rich substrates with bright lighting. A nutrient-rich substrate helps to maintain healthy growth. In this case EcoComplete, fluorite or laterite should be added as your regular substrate. Lighting should be at least 2 -3 watts per gallon of water using full spectrum (5000-7000K) bulbs for about 10 to 12 hours per day. More lighting also causes algae to grow on your Amazon sword leaves. To remove algae from your tank the Siamese algae eating sharks and the algae-eating shrimps should be added in the tank. In this case dwarf sucker catfish (Otocinclus) can help a great deal also. Never add a Plecostomus, silver dollars, goldfish,Texas Cichlids, Oscar, Jack Dempsey and big cichlids because they eat the leaves or damage the root system of the plant. Regular doses of an iron rich fertilizer should be added weekly after a water change. During water changes check the damaged and torn leaves. Because this plant cannot repair damaged leaves and it should be removed to allow the plant to redirect energy to the healthy leaves. The aquarium water temperature should be ranged from 71.6 – 86°F (22 – 30 °C), with a hardness of 4 -18 dGH and a pH of 6.5-7.5. 10% of your aquarium water should be changed per week. To keep your tank environment healthy, regular water changes not only prevent the undesirable accumulation of excess nutrients, but also remove excess nitrates and waste products of the fish and plants.
