Are UV Sterilizers worth the investment?
Some people swear by them, personally I haven't used one in about 5 years.
Very little, ick is a large organism and sometimes will make it through an appropriately sized UV
with nothing more than a sunburn. Also UVs can only kill what goes through them, it will have no effect on the ick on the fish.
I have a tang that has alot of white spots suddenly, still eating fine and swimming all over the tank. No other fish have any spots.
Was wondering in the UV Sterilizers might help the fish from getting ick when stressed.
The best advice I can give is to quarantine all fish when you get them, treating prophylactically with Hyposalinity
, this will prevent the introduction of ick into your system. At this point in time you need to treat the tang and every other fish in your system in a QT
for ick, leaving the display tank fallow for 4 weeks to insure all the ick in the display has died.
