I guess it all depends on what you are doing. Good luck

Sorry, I have to correct this. If your tank was zero nutrient it would die. ZEOvit encourages low nutrient tanks.

UV sterilizers have their place, which imo is generally on a quarantine tank. In order to kill pathogens though, the wattage has to be much higher than most people think, and the length of exposure needs to be longer as well. For these reasons, UV sterilizers are usually only good for killing algae which is more sensitive.

On a QT I like to run a UV wattage that is 10x the capacity of the tank. So for a 30 gallon QT, get something close to 30w, then have 3x the wattage for turnover, so in this case about 90 gph. I wouldn't recommend this for a display though, it would kill too much beneficial "stuff".
