Korallen Zucht, makers of Zeovit, came out with Coral Snow not too long ago. Given the reported effects we thought we would give it a try. Here’s what Pohl and KZ have to say about the product:
“Coral Snow is a liquid form secondary biological facilitator for elements such as Bbalance and Potassium-Iodide/Flouride Concentrate. It is also compatible with Amino Acids and Coral Vitalizer.
Coral Snow contains a natural calcium-magnesium carbonate among other ingredients. The particles as well as the other compounds can be taken up directly by the corals. Coral Snow neutralizes unwanted acids and yellowing compounds and can be beneficial in the prevention of e.g. slime algae and cyano bacteria.
We dose Coral Snow daily, every time with a different element, The necessary amount of Coral Snow is poured into a small container and mixed with the to be dosed element. Gently mix and let it sit for about 5 minutes. Then add it directly to the tank at an areawith high water flow. You can use 0.5 to max. 4 ml Coral Snow per 25 gallons daily. The initial cloudiness is not harmful to fishes or even the most sensitive corals.”
Coral Snow is a mineral flocculant that took some time and tuning to convince us it was worthy of buying again. When we first started using Coral Snow, the only positive effect we noticed was an increase in water clarity. Not a bad thing, but the clarity decreased with time and we were hoping for a bit more.
At that time we were dosing it everyday, which we found to be too much for our system. Water clarity didn’t increase like it had from the first few doses and it took almost an entire day to remove the cloudiness. Since switching to M-W-F dosing, it’s effects in conjunction with Vibrance (Potassium Iodide) and other supplements has been magnified and the system can remove the flocculant in a few hours.
Currently we dose 1.5ml Monday, Wednesday, and Friday. When doing tank cleaning or notice nutrients rising, we double the dose to 3-4ml. When dosing we add Coral Snow into a small glass bowl, as shown in the first picture and add Potassium Iodide and Amino Acids to the CS. We let this mixture sit for the recommended 5 minutes and then add directly to the display. (Quite a bit “sticks” to the bowl, so we also dunk and swish it to remove the remaining Coral Snow.)
After dosing this is what the glassbox looks like.
The fish and corals do not mind at all. In fact when adding it the tank our fish often think it is food and have swam through the direct solution as it’s being added with no ill effects. Still, we suggest adding it to a high flow area of the tank to disperse the solution as well as possible… just to be safe.
Our DAS EX-2 skimmer removes the Coral Snow well, taking out other nasties with it. We try and clean our glass just after dosing to help remove the released algae and nutrients. I have no idea if this works or not, but the timing of it works well for us. This skimmate is very chalky, murky, and opaque. To be honest it’s just disgusting. This is just 2 hours after adding Coral Snow to the system.
This is quickly skimmed out creating a cleaner, crisper display tank. Here’s a close up of the skimmate… Yum? Edit: Bob (Aged Salt) on the friendly Zeo Forums informed us that Coral Snow is completely free of Al. We’ll take his word on it.
After feedings or sticking our hands in the tank, we have found that Coral Snow can rebuild the foam head quickly.
Overall we are very happy with the results. The increase in clarity, when combined with activated carbon is very impressive. We went two weeks without dosing and noticed an increase in algae, and colors fading in our Acroporas… since resuming the algae is going away and colors are coming back. Granted we also dose a small amount of KI and AA’s, but we feel those changes are worth noting. We do not feel it will eliminate algaes, but we do believe it will help contribute to a low or “ultra low” nutrient environment.
Gary White (mesocosm) and others have brought up the role these “transporters” can play in delivering trace elements and food sources to the corals. I can’t say this is what has happened, but the results are strong enough that we will continue to use Coral Snow in the future.
