We have had our tank for about year and upgraded recently to a 70 gallon. Our nitrate levels are a little high, but hubby recently purchased a filter for the "water change water" and its bringing the level down slowly with each water change w/ the filtered water. However, we have noticed an increase in "anatasia" - I think that is what they are and they are spreading like wildfire. They are brown tublar anemone (circular shape at the head with the tentacles). We had a couple on a live rock we purchased. Now we have a ton of babies growing all over. How do we get rid of them? Is there a natural predator? Is it because our nitrates are high? Will they go away with lower levels water? Oh, please help. They are ruining our viewing pleasure. We have muchrooms and corals, a couple tangs, couple star fishes, couple clown and one dotty back, and several dusty feathers.
