I have read many different views about the use of a UV sterilizer on tanks. The people who oppose it tend to oppose it on the grounds that a UV will kill the good bacteria along with the bad bacteria. And while that may be true, I have heard enough talks now to make me think that doesn't matter. My understanding is that most of the good bacteria in our tanks is concentrated around the corals and to a lesser extent the rocks and sand. If it is not free floating, it will not be killed by the UV sterilizer.
With that thinking, I added a UV to my tank about a week ago. In the last week, I have noticed two things that have happened to my tank:
1) there has been a marked decrease in the amount of cyanobacteria in my tank. I've been fighting a bit with the cyano recently, and it is definitely reducing.
2) there has been an explosion of isopods in my tank. They are everywhere. I have to scrape them off of my glass in the mornings. I have a fat fat mandarin.
While I can understand why this seems to have caused my cyano to decrease, I can't figure out how it would have affected my pod population. Do you think it's just a coincidence?
