The Rain Bird ACS is an environmentally-safe algae control system that uses state-of-the-art ultrasonic technology to kill algae without harming other aquatic life such as plants or fish. The ACS transducer, submerged just beneath the surface, is programmed to generate ultrasonic waves that inhibit the growth and spread of algae. You will begin to see results from within a few days to three weeks, depending on the type of algae and how much algae was established in your water site.
It is important to keep the transducer head clean and free of algae or other scum buildup. We recommend that at least every 30 days you unplug your ACS device from the power source, take it out of the water, wipe the face of the transducer off, put it back into the water and plug it back in. In most applications, once a month cleanings are sufficient, however, in a new installation you should check your unit(s) after initial two weeks to see if more frequent cleanings are necessary. Failure to keep the face clean will interfere with the ultrasonic waves and result in reduced effectiveness of the device.
