The lighting is two double tubes of flourescent lighting..the tests i did today are fine the ph is a little low but part form that no problems with the rest.. the anemone is actually a white one.. ..the nudibranch is directly in the middle he is a Cyerece, he is see through with some little orange marks on him ..looks like little leaves, maybe what you thought was algae.. he gets around that tank haha..the tank did cycle and i nvr had any issues with he parameters until yesterday..i will have a read throught the stuff you recommended
What kind of anemone?
