I used FM for about 6 months or so. After the first ultralith rock change I experienced a brownout of corals that was never really fully explained. I continued with the product and coral colors rebounded after about 2 months now (about 3 months into using the product). Any subsequent rock changes were done without any problems and I never did figure out what happened. During the time I ran FM, I never saw the great colors that were experienced by others, some corals were looking pretty good but they mostly looked like they had before I started using the product. During this time I had heard about a couple of zeovit products, Coral Snow and Pohls Coral Vitalizer, and decided to incorporate those into my daily dosing. I'd say within 7-10 days (no lie) I saw my corals start to color up like they hadn't done with the FM product. I continued on with FM as I wanted to give it a full 6 month trial. However close to the end of the trial a zeovit reactor with some supplements became available to me for a really good deal and I jumped on it.
I'm into my 3rd week with zeovit now, corals are getting more colorful each week it seems. I'll give zeovit the same 6 month trial but for sure I think its doing better than the FM although its too early to tell and I'm not yet at that first rock change.
Now I'm not saying that FM isn't the one for you, it just wasn't the one for me. I found that when I was running it there wasn't much support out there for it online. Someone had started a website (
www.ultralith.com) however it is poorly supported. There is also a FaunaMarin forum now at ReefCentral which has better support. At the time I was having problems it was like pulling teeth to get some help. However, some people certainly have great success with ultralith, there are many photos of successful tanks online. Wendell at Ocean Aquatics was running it on his SPS display tank and the colors were incredible. I just was unable to achieve that. I strongly suspect I might have without the brownout at the first rock change. It was just taking too long to see results and I felt I was just pouring money into something that wasn't working for me.
Anyway thats my fifty cents
