Native to southeast Asia, Java Fern, Microsorum pteropus, is found attached to roots and rocks in streams and rivers, along riverbanks, and in marshes. Rhizome should be anchored to wood or stone. If planted in substrate, ensure rhizome is never buried, to avoid rot. Leaves grow 6-12 inches dependent on available nutrient. Thrives with regular fertilization. Black areas on leaves are sporangia, reproductive organs, not necessarily symptom of deficiency. Transparent areas on leaves are a result of too much light. Medium light is sufficient for optimal growth, excellent growth in diffused light. Water circulation / current is essential to optimal growth.
Java fern reproduces by adventitious plants at tips of leaves. After plantlets develop several leaves and roots, they can be separated and propagated. Propagation also possible by cutting rhizome, ensure that leaves and roots attached to each section. Capable of emersed growth in humid conditions, rhizome must remain in water and leaves require sufficient moisture in air. This plant is not eaten by herbivorous fish.

Seachem Reef Reactor Lg
Reef Reactor™ is a high-purity source of aragonite, which supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria. It has a grain size of approximately 1-3 cm. (Reef Reactor™ Md is 0.5 - 1 cm). It is intended for use in calcium reactors where it is dissolved slowly with the addition of CO2. As it dissolves, it provides calcium, magnesium, strontium, potassium, and carbonates among other important elements for reef aquaria. It is excellent at increasing and stabilizing alkalinity, which also supports a stable pH and encourages the rapid formation of coral skeletal material. With high levels of both calcium and magnesium, it offers an excellent means of balanced supplementation for rapid growth and propagation of corals and calcareous animals in reef aquaria. It possesses the highest level of soluble potassium of all competing brands while exhibiting the lowest levels of both aluminum and phosphorus.
Rinse Reef Reactor™ prior to initial placement in your calcium reactor. The rate of water flow through the reactor in conjunction with the pH of the water inside the reactor will control the rate of media dissolution. Follow the manufacturer’s instructions furnished with the calcium reactor and adjust the rates of water flow and CO2 injection to attain the desired concentrations of calcium and alkalinity in the effluent.
Use Seachem’s Reef Status™: Magnesium and Reef Status™: Calcium test kits to measure alkalinity, calcium, and magnesium concentrations.
