These temperatures should be carefully maintained as they are not very tolerant to intenseheat or cold Light:Marimo Moss Balls are adapted to low-light situations. They will not handle direct sunlight, and will burn and turn brown. Keep away from windows as glass will focus the light and make it more intense, as well as increase the water tempurature Watering:The water should be changed once every 2 weeks using regular tap water. For best result allow the tap water to sit out for 24 hours to evaporate any chlorine. During the summer there will be more evaporation of water, so water may need to be changed more frequently
