<p>I just tested this sterilizer and it is in working order. &nbsp;I replaced the bulb and it has about 2 weeks of use on it.</p>

<p><span style="background-color:rgb(238, 238, 238); color:rgb(0, 0, 0); font-family:verdana; font-size:11px">The Aqua Medic Helix Max 18 Watt UV Sterilizer uses an aggressive spiraling flow design that incorporates more &quot;twists&quot; in a single pass through the housing. This increase in contact time means big gains in efficiency. The 18 Watt Helix Max is appropriate for aquariums from 125 to 300 gallons. A pump is needed for the sterilizer. The flow rate through the sterilizer must be less than 400 gph.</span></p>
