Thank you I love straight answers.You don't need it. Minimal value to the most systems.
I see your point. But my tank is only 25 gallons, I really don't think that's enough room for a tang. But I like the idea of nuking at first site...Any expected tangs. If yes. Then the answer is
hell yeah !!!! One stressful event will result in an Ick outbreak that will kill the tank.
You don't have to run it 24-7. But when you see that first white spot. Turn on the nuke !!!!
That's what I heard as well. But some believe that it won't kill every and if not left on constantly the good bacteria will regenerate. So I asked won the bad regenerate as well?I have heard both sides and both sides sound good. The main reason I don't run one (and yes I have Tangs) is it will kill everything in the water which means even the good stuff.
