UV sterilizer - for Ich and algae. My experience

will the UV kill the copods and BBS in the tank? Won't they pass through also?
Unless they get to the bulb - no. If youre running an in tank - that increases risk but most external units are suspended
 
Why does Leucosternon seem to no longer have dots in the evening, and is full of them in the morning? He eats, but I can't solve it... I can't take it out... How can I intervene?
