Increases clarity/no discernible effect on cyano By Jim on 10/8/2016

On the one hand, this product does significant'y increase clarity when dosed daily. I am now on my second 250 ml bottle. It has no effect on my tank's pH, but does increase the volume of skim mate. I use it to improve water clarity, together with Zeolife, because I cannot use activated carbon. That gives my Yellow Tang Lateral Line Disease. On the other hand, I occasionally fight cyano, and this product has no discernible effect on whether I do or don't develop or get rid of cyano. Does not bother me because I did not purchase it for that purpose, although it is advertised as cyano cure. As usual, Korallen-Zucht makes no disclosure of the ingredients, so you just have to try it to see if it works, and then speculate as why it does or does not. That's irritating, at least to me.

With the combination of coral snow and cyano clean I've cleared up my cyano outbreak... But my turbo snails are not doing well. Every day I need to reattach half of them to the rocks. Not sure if it's from the kz products or posably a rise in nitrate from the cyano dieing.
Use it all the time By Terri on 6/6/2015

I like the K-Z products because I do not see changes in tank nutrient levels ;0) Use the Coral Snow along with other K-Z products such as Vitalty, etc. Good products from Germany!
Removes yellow tinge By Nathan on 2/3/2015

This does remove the yellow tinge in the water for me. But if you use it, be sure to use it at night or on a day when no one is going to come look at your tank. Also make sure your wife/significant other knows that you are doing something like this so they don't get worried on your part ("Nathan! something is horribly wrong with your tank! Come Quick!").
I don't know if I get enough out of it to spend the premium money on it again when I could use carbon.

just make sure to use at night, takes a couple of hours to clear out, but when it does it really clears up the water

used this product for years with and with out Cyano issues, it was the only thing I would put in my tank for a long time.

The first time I used this product it surprised me on how dirty the water was. I use this twice a week and it keeps the tank looking like new. Make sure to do it after lights out, it will cloud the tank.
Works to clarify By ray on 6/5/2014

I have a pretty decent tank and thought this could hurt to try. Used for a few days and noticed a discernible difference in clarity. I always thought my water was crystal clear, but after using this it was amazingly clearer.
I like it By Trevor on 4/21/2014

It is a really interesting product. A capful will produce whiteout conditions in your tank for several hours, which is why they recommend you do it at night. It doesn't seem to negatively impact any corals or fish. Also I did notice that I had less cyano/brown algae when I was using this product once a week.
Overall it works pretty well and leaves the water looking clear. I will probably buy it again.
A noticeable product By Jake mills central IL on 2/23/2014

For a few months i had been fighting a cyano outbreak and between coral snow and KZ's other cyano drops I was able to start beating the outbreak down without having to use other products as chemiclean orem tablets... and to top it all off my clam had opened up twice as much after I started using this product...so if you want to spend a couple extra bucks for a product that has noticeable and completed gains then the KZ'S products are the way to go!
