Coral Snow liquid will help with yellowing compounds that activated carbon misses. It has also been shown to be beneficial in treating unwanted slime algae and cyanobacteria. The product contains natural calcium-magnesium carbonate and other specialized compounds. Clay-like composition and properties make for a highly absorbent medium that can be taken up by corals and protein skimmers.
This is primarily a secondary biological facilitator for other Korallen-Zucht products like Amino Acids Coral Vitalizer, B-Balance and Potassium-Iodide/Fluoride Concentrate.
Dose Coral Snow 1 mL per 25 US gallons every day mixed with a different product to enhance results. Combine the desired amount of Coral Snow and additive, rest for 5 minutes then add directly to a high flow area of the tank. Initial cloudiness is normal and not harmful. After initial cloudiness disappears you will notice the water is extremely clear, very similar to when fresh activated carbon is added to the tank. Do not exceed recommended amount.
To help eliminate cyano bacteria add one drop of ZEObak per 25 gallons of tank water to Coral Snow. Dose every two days until cyano bacteria is gone.
SAVE YOUR MONEY By DavidS on 6/12/2017DavidS wouldn't recommend this product to a friendCoral Snow and Zeobak are Korallen Zucht products that can be used as standalone products.
I've used it in the past to 1. feed my corals,2 improve water quality and 3 to get rid of nuisance algae/cyano.
In my previous use, I could not attribute whether or not my corals benefited but there was no appreciable improvement in water clarity and there was no decrease in microalgea.
Recently, I had a Cyano attack in my display (38 gallon) and tried using the Coral Snow and Zeobak again.
After several weeks of dosing them there was no improvement in the Cyano. I have since seen a large improvement by 1. shortening the lighting period by 1 hour and using a Kessil H80 to grow Chaeto in my Aquafuge. I also stopped using Coral Snow & Zeobak.
If you are looking for a bacterial product, there may be other sources that are cheaper and as or more effective.
Excelente By Saul on 3/11/2017Saul would recommend this product to a friendThe 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 well when combined with Zeoback - But you need a strong skimmer By Jared on 3/8/2017Jared would recommend this product to a friendThis stuff works very well to remove cyano when you combine it with Zeobak. I let them mix together in a cup for 5 minutes before adding. I dose at night because it takes a while to clear back up. Make sure you have a strong skimmer, or you will not get the full benefit. For me it did not cause the skimmer to overflow, but improved the "sludginess" of the skimmate. I found that emptying and cleaning the skimmer cup after 24 hours helped, as the sides of the neck were caked with sludge.
Increases clarity/no discernible effect on cyano By Jim on 10/8/2016Jim would recommend this product to a friendOn 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.
Be careful. By Ryan on 1/21/2016Ryan would recommend this product to a friendWith 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 6/6/2015Terri would recommend this product to a friendI 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 2/3/2015Nathan would recommend this product to a friendThis 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.
crystal clear water By Arash on 12/19/2014Arash would recommend this product to a friendjust make sure to use at night, takes a couple of hours to clear out, but when it does it really clears up the water
have to use this By Gaspare on 10/11/2014Gaspare would recommend this product to a friendused 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.
Super Clean By Jonathan on 7/16/2014Jonathan would recommend this product to a friendThe 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 6/5/2014ray would recommend this product to a friendI 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 4/21/2014Trevor would recommend this product to a friendIt 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.

This will not have a negative impact on bio pellets. Feel free to let us know if you have any further questions!
ZeoBak is typically only needed in conjunction with the Zeovit System and Zeolite media. Most zeo products are intended to be dosed into the Zeovit reactor directly and dilution beforehand will not be required. Feel free to let us know if you have any further questions.
