UV lights and algae. 

We got a bad case if spore algae and the water turned green. Thanks to the helpful videos from Aquarium CO OP we figured out the cause. (Plants and fertilizer came from Aquarium CO OP).   We eliminated the algae spores with a UV light filter. The question is, now that the algae is gone do we need to run the UV light in the filter all the time. It has the ability to operate as a power head with out the light on. My concern is I do not want to impact other aspects of destroying beneficial bacteria etc. I was thinking operating the UV light 24 hours every week if needed. What say you?

What I do is have it on for 24hr at first then gradually reduce the amount of time its on you will get to the point were you will only need it on for couple of hours a day
