uv sterilizer

[ungwhat]

does anyone have one on their setup and if so was it worth it?

i ran a large one for a few years but found no benefit from it. its been out of the tank for at least a year and no change since removing it.

if your thinking of adding one to help control decease or parasites you must remember that most of these are found on the fish, coral or substrate. the only way UV can be effective is if what ever you are trying to kill go's through the UV.

IMO they are not worth it. spend you money elsewhere
