Can you guys give me some advice on purchasing a UV sterilizer. I have a 40 gallon mixed reef. I am looking at a hang on style. Does anyone know much about an Odyssea Sterilizer? I am also considering a Lifeguard or Emperor Aquatics. I have looked at anything from 8 - 25 watts.

Thanks

american counter parts need to chime in for this one bud on specific brands.

as for the wattage though, 8 watt will generally do 170lt tank with a flow rate of 700lt per/hr

25watt on the other hand will be good for 400lt tanks with a flow rate of 1750lt per/hr


so for a 40gal , 8 watt would be perfect, the question id be asking cause the units aren't the cheapest, is will i be looking to expand volume in the near future. if the answers yes, then buy a stronger model. you can even buy a higher watt model even if your not looking to upgrade, or you can run units in sequence at a latter date. sterilisers are pretty versitile, just have to get the flow right & at the correct wave length or they are a waste of money.
