This is the brand has been used on many commercial purpose, I did a lot research on what are the best UV out there, Emperor even advertise their output lower than what they are actually producing, don't buy cheap units thats made for profit only. You get what you pay for!!
Poor Performance By Joe on 1/3/14

I put one of these 80 watt units on a 150 Gallon Tank and verify I was pushing 460 gallons per hour thru the unit. I'll admit I thought I had the world beat sine the unit is rated for a 600 gallon tank. So I got fish and put them straight into the display tank. It turned out they had ICH and this breakout was NO DIFFERENCE then any other time. It was as if the unit was no even in the system.
Sure I should have put them into the QT but you would think since this tank is 1/4 of what it is rated for it could handle it but like I said I saw no difference.
The money would have better spent making my QT better.

I have been using this unit on my tank for 2 years now on a 200g twv system. Prior to this, I was using a 40w Aqua UV and had the tank completely wiped out twice. Once with ich and once with velvet. Four figures in livestock loses.
In the two years since running the Emperor 80w HO on my system I've not had a loss since. My water clarity is pristine and only need to run the UV during "lights on" periods to achieve success.
Oversizing the unit for my tank allows me to get twice the bulb life saving money over the longterm. I bought a much larger unit than my tank needed for future upgrades. You can't go too big with a UV on your tank. So, bump up one size from what you think you need and let it rip on your tank and future upgrade!

I installed this sterilizer on my 300 gallon reef system after a algae bloom. In 24 hours the water was clear
