I bought this because of the reviews. I like to mix it with ZeoBak, Coral Snow, Zeostart, and Biomate. I almost make a cocktail that I let sit for hours. It's like an energy bomb on your tank. I use a lot of bio media and carbon dosing and this stuff clearly helps. I also have a little cyno in my sump. It doesnt work like some of the red slime removers but I don't trust those in my reef. This stuff when added routinely beats the cyno down. It goes a long way and is definitely worth the money.

This stuff works, just as the other reviewers said. Take note to let it dissolve in your tank water for 6-8 hours prior to dosing. I recommend doing this overnight, and then adding in the morning. I would also recommend being home to monitor your skimmer activity, as it may increase. My only complaint is that the directions say to add 1 scoop for 250gallons. An accurate scale would be needed to figure out how much would be needed for smaller volumes. Example - weigh a full scoop, divide by 250. Multiply this number by the number of gallons in your tank, and then weigh that out. Maybe I'm a little too exact, but I doubt most people have 250 gallon+ tanks.

I have been battling Cyano breakouts on and off. I run carbon and GFO in a reactor and I generally don't have issues with the green stuff, but the evil red slime would make random appearances. I tried ZeoZym this weekend per the treatment, not dosing directions. I can already see a difference in my water clarity. The cyano is rapidly disappearing and my skimmer is more disgusting than ever. We will see long term, but the first impression is a good one.

Tank is cleaner than ever! This product is making my skimmer work even better than it did before. I wasn't sure about getting this when I ordered it but very glad that I did. Simply awesome!

So i bought this product about a month ago from BRS. And it works like a charm. Yes there are steps to use the product but after a couple days. You can see darker skim mate then before. Sometimes i even pull thick black slimy stuff out of the collection cup. I assume it must be cyano that was on my sand bed which disappeared. You have to be patient will this product because it slowly works its way with helping out the protein skimmer.
