Anthuriums require little care, and bloom almost continuously in good conditions. It likes bright light and needs to dry out between watering, making good drainage essential. I would try letting it dry out some between waterings. Does the water you are using have chlorine or flouride in it? If so that could be part of your problem. If so let the water sit in an open bucket for 48 hours to allow the chlorine and flouride to evaporate.
To get continual blossoms, you will need to use a blooming plant food. Look for a food where the middle number is the largest of the three numbers, representing high phosphoric acid content. When the first number, representing Nitrogen, is the largest number, it is good foliage plant food, and the third number, representing Soluble Potash, is for stronger root development, which is a good transplanting food. Feed your Antherium every other month to ensure a healthy blooming plant. With the Anthurium, as with any houseplant, the more light, the more foliage, the more water, the more plant food.
