I started up my U-V light yesterday & this morning my rays are all very lathargic & not eating for the first time EVER! I did a test & there is an ammonia spike. I am doing an 80% water change, but what else should I do? Unplug the U-V? Is it the cause of the issue?

I can't see how the uv could cause an ammonia spike but if that's the only change that has been made, it would have to be. I would leave it on and monitor closely throughout the weekend. In the end, the uv will do fare more good than harm.

My fish guy says the U-V only affects things that go past it. We did not have the U-V running before because we let the tank cycle & the bacteria colonies could grow. Now we are sterilizing them. The bacteria that maintain the ammonia level live on a surface area; like the filter, rocks & sand. So water changes & prime?
Basically, yea. Uv shouldn't affect bb at all. Maybe it was just coincidental, a little mini cycle?

Well I did an 80% water change & turned the lights out. I'll go back after dinner & test the water again. Hopefully they will have perked up some!
Second thought... is the uv new or used? if it is used it is possible there was old gunk in it that fired in to the water.
