The Exo Terra Monsoon RS400 is a programmable rainfall system suitable for all types of terrariums and greenhouses. It helps maintain optimal humidity by generating precipitation at programmed intervals. The duration and frequency of precipitation can be easily adjusted depending on the type of animal or plant housed. Frequent rainfall helps stimulate breeding behavior, and is a necessity when housing live tropical plants such as Bromeliads, orchids, and mosses. The system can be programmed to rain multiple times per 24-hour cycle, for time periods ranging from one second to two hours. The large one gallon reservoir ensures continuous operation for several days without the need for refilling and the reservoir can be easily replenished without needing to uninstall the entire system. The Monsoon System is ideal for when you are going on a vacation and want to ensure a proper watering system for your pets. The Exo Terra Monsoon RS400 comes with two easy-to-install nozzles, but the system can be extended to accommodate up to 6 nozzles, making it ideal for multiple terrariums*. To connect additional nozzles, an extra nozzle and a Y-connector are needed (sold separately). Simply cut the tubing where convenient, preferably as close as possible to the first Y-connector and make sure the nozzle can easily be mounted in its intended location without stretching the tubing. Connect the tubing coming from the unit to the single hole of the Y-connector and the other end of the tubing to the double hole. Finally, connect the tubing from the additional nozzle to the other hole of the Y-connector. *Every additional nozzle will result in less performance from each nozzle installed. Product FeaturesFlexible spray nozzles can be pointed in any direction Easy to install tubing; fits through the closeable wire/tube inlets (featured on all Exo Terra Terrariums) Easy to connect and install Sloping top; makes filling water reservoir easier The presence of clean and fresh water is important for the proper care and maintenance of captive reptiles and amphibians. The Exo Terra Monsoon helps ensure that a quality water source is always easy accessible for the terrarium inhabitants and that the water is kept clean and free of debris. Maintenance It is advisable to place the unit in a dark location or otherwise shielded from light to prevent the growth of algae in the reservoir. Should algae form, just wipe the inside of the reservoir with a damp cloth. Do not use detergent or solvents as it might harm your terrarium animals! Make sure to discard any dirty water or water containing debris or particles. Only use de-mineralized/distilled water or debris-free and clean rainwater. Replace the filter regularly, at least every six months depending on the usage and water quality. If the nozzles are clogged or if they spray irregularly, place the nozzles overnight in a 50/50 water/vinegar solution. Rinse thoroughly with clean water before mounting the nozzles back onto the terrarium. If the problem persists, replace the nozzles. Replacement nozzles (PT2501) and filters (PT2500) are available separately. The Exo Terra Monsoon RS400 should be set according to the needs of the animals housed and to the size of the terrarium. Be careful not to operate the unit too frequently or too long to avoid overflowing the terrarium. The unit should be set so that water added to the terrarium from the first operating cycle is allowed to evaporate before the next operating cycle begins, or at least make sure that the excess water can be drained out of the terrarium.
