The Turbotwist is working

#1
First..thanks to Ed, Amin and everybody who has helped me through this difficult altum journey...that is not done yet...

Another question...now that UV is on...is it on all of the time...my tank is sparse ( will send pictures when I get the alturms next week...so I want to keep it as free of algae as possible...is it when the tank lights are on or what...Ishould know this but I'm just not sure...24/7?

Also, I am running an Eheim Ultra 160 filter...when and how do I clean it without losing my long fought- for biofilter...next question under " other fish"...Thanks...Ken
