Hi guys, I just installed an 11w uv sterilizer and the next day there was a big patch of a yellow/mustard colored film on the live rock and the overall color of the tank is a green/yellow look,haveing said that the water is very clear and the skim in the protien skimmer is very pale and not as dark as it has been,we have also had a couple of morph detatch from the rock and are now just floating around the tank ,I have turned of the uv till I find out what is going on
thanks for any help here guys

Wow,never heard of that before? I run two 57w uv's and have always ran UV for +20 years. Was this a new unit ? What unit is it ? Did you notice a temp swing ? Spikes in levels? The yellow film sounds diffren.
There hasn't been any temp change & unfortunatly I work away from home (wont be back home for another 2 weeks) so I have not had the chance to do any levels since the yellow film appeared,its about 12"x6" right in the front & centre of the tank ,if its still there when I get home I'll post some pics,it litteraly appeared over night, does it matter which way the water flows through a uv ,I would have thought not but hey,maybe ,I just had a look at the web site selling the uv and it shows the water flow going one way but I have hooked it up the other way ,hmmm ,what do you think ?
