I know using a UV filter in the wrong manner can be very bad for your tank. I heard it can even lead to things like new tank syndrome. I have a UV filter and I have heard that it can help keep the water clear, however I want to make sure I know how to use it properly and safely before I use it. It is a 13 watts UV light bulb in a fully submersible pump that runs at a little over 200 gallons per hour. It would be residing inside of a 30 gallon tank. The water flow is adjustable so it does not have to be a full 200 Plus gallons per hour. I do not believe my tank has gone through his first full cycle as of yet. considering that this thing will destroy good and bad bacteria, I have decided not to implement it as of yet. I would however like to know how and when to go about doing so. any thoughts?
