Just had my UV
lamp replaced, bulb blown.
While at my favorite aquarium store, consulted the guy there about duration UV
needs to turn on. His immediate reply was off it as soon as the
water clear up. Well, after learning that my tank is not cloudy he
suggested to on when the needs arises. So there is no need to on it
24/7. I have it hook to my lighting timer, had the pump on automatically.
had another switch, so will on it whenever I need it.
Verdict: Still unsure.
