almost got it all :)

As done by others on a site of the same name as the product (sorry cannot post urls to other forumns), others with Zeo that do use Zeobac have had success with UV usage. What they do is tend to turn off the UV for 1-3 hours when ZeoBac is added. (I will state that there are mixed reviews, but again it is being done)

Here is a quote from that site from a well regard ZeoHead and Admin for this ZEO site:

"Hi (name removed), you can use it temporary, just switch off the UV for about 1 hour after you have dosed ZeoBac."

Now this is what I can tell you has happened with UV and Zeovit. Before UV I had a plankton issue, I had alot and the fish loved it, but I didn't because it also assisted to some algae development and green water. Also I had some coral tissue regression. Even with regular water changes and testing, my tank specs were within proper levels, but I did have this one issue. Since adding the UV, the plankton issue is gone, algae on back wall also almost gone, water is clear and coral has taken off . Yes... the coral is growing quite aggressively. (My tank is majority SPS)

So in my case UV is working even with ZEO...

Remember the main purpose to forums, they are not just for the basics, without some expirementation there isn't any progression in the hobby. Remember others in the past have done things that they got bashed for and today what they did may be a standard practice. This is for many things in life so again remember the purpose of forums, if they are the same blah blah blah from everyone then what is the point.

Have fun all!!!
