Using this item to provide extra aeration to my koi pond for treating filamentous algae. Setup was quick and easy. All necessary check valves, hoses, etc. were included. It has been running nonstop for over a month now without incident.Only caveat is that the unit must be sheltered from the elements, despite the fact that the pond is obviously outside! Luckily, the hoses are fairly long, which gives one much flexibility in locating the unit. Another important note: The aerating discs float and are very light, so one must weigh them down or affix them to the bottom for proper aeration. Unfortunately, bumping the hoses can cause the discs to be displaced fairly easily.Overall, very effective product for the price.
