In general, apply Fountain Perfect weekly, every week, during seasons where algae build up and poor water quality are typically a problem. Fountain Perfect will reduce required fountain cleanings by 70 to 80%).

Fountain Perfect contains concentrated biosolids, and treated water may look cloudy for a few hours after application after which the water will clear). Fountain Perfect is not a chemical, and may take a few applications to solve difficult problems.

If starting off with a severe problem or for faster results, we recommend cleaning out the water feature and the water reservoir before dosing, starting fresh, and then immediately applying Fountain Perfect once a week. It is best to apply in the evening, to avoid sunlight sunlight. Storage & Shelf Life »
