You did not answer any of my first questions and until I know these levels I would not offer any advice about what you should add .But until you know the main water parameters of the tanks levels then I'd not add any thing you have to know the Ca. Dkh and Mag . Levels then t know the NO3 and PO4 is also a must You did not . No matter what species that anemone is its so faded it is hard to tell really and the fact you have it under 4 26W P/C is almost a certain death warrant and if you have tried to keep any previous anemones then they soon met their demise I'm sure .. The tank at 9 month is a tad young for an anemone and You really need to test the water levels.. Forget about iodine is not needed at all and anyone who would just add it and not test the levels then thats a major mistake like adding Ca and Buffer and Magnesium with out knowing the levels.. There are certain rules that have to be followed and applied and I think you jumped over more then one or 2 of them. Test the water parameters and post them and I'm sure many here can and will help you .. And watch out for the anemone its looking rather pale.. As I said I can see by the looks of the rocks that either one of the other or both the Ca and Dkh are low and Magnesium is important in these levels. Post the results and I'll tell you what I'd add as for the coral Buff I have never heard of it and not sure what it is do you have the name of the manufacture and what the labels says its for and any directions of usage and dosing ?.
