Just keep in mind, and why I feel identification is irrelevant. Its not that LC's are immune to UV (they don't have armor), it's that they don't voluntarily go into the water column. They embed themselves to the sand, which makes it very hard to force them away. If you have them on your rocks, and are able to move them freely into the water column by blow them off with a turkey baster, a UV will kill them. Regardless, if its on your rocks, you can assume that you have more than one type of dinoflagellates, which UV will treat. We already know he will need to dose silicate for the sand. I had ever type imaginable.
I can turkey baste 50 times a day if I need to to keep those suckers floating in the water to get irradiated.
Do you think this type of UV filter sterilizer would be sufficient for my 45 gallon? It says it does up to 80 gallons. Thanks again for your help.
