If I were an english teacher, I'd probably be reprimanding you right now for that huge run-on sentence. =P
The "brown algae" may be diatoms. If that's the case, then you have silicates in your tank (diatoms feed on silicates). What type of water are you using? If it's tap water, then that's your problem right there.
Your anemone is dying under that lighting. They need much, much more light than that. Corals also require a lot more light. :happyfish
