What do you think of my set up?

OK guys about 2 monts ago i knew nothing about the saltwater part of aquariums. I have kept freshwater for about 5 years now. I converted my 55 gal. freshwater tank over to saltwater about two months ago. Anyways...I started out with 50 lbs. of live sand, a skelter hang-on filter/skimmer that filters about 400 gph. (It says its enough for 55 gal.) I also have a standard 30 hang on filter on, filtering about 200 gph. And also a Powerhead in the opposite corner moving about 375 gph. The water is well oxogenated but the skimmer and the powerhead. I have about 15 lbs. of liverock in there that i got at my LFS. I have about another 8 lbs. of just rock in there, I have also put some fake plants in there for some hiding places and just cause it looks good seeing the plants sway with the current. I have Standard 15 watt. lights that came with the tank. OK i think that covers the tank part of it now for my fish. I started with 4 blue damsel's to get the tank to cycle, ended up in 3 of them dying. bummer. After everthing settled down i got a domino damsel. Things were goin good for a while then i got this nasty rusty algea bloom all over everything. That prompted me to get some cleaners. all i could afford at the time a coulple of hermit crabs. I also put my lights on 8 hour timers to help try to contol this too. Algea is still kinda a prob but my fish like it too. Everything seemed to be goin well so i decided to get something cool to look at. Probably not the best idea but i got a snowflake eel. He is small about 5-6 inches i have got him to eat freeze dried krill as well as live guppies. Yeah i think that about covers it..we seem to be up to date now. I am just wondering what i am doin right what i am doin wrong? How much live rock do i really need? Do i have enough filtration or too much? what is a good cleaning crew? what kind of lights do i need or are mine fine? There is all sorts of questions that i have i cant ask them all now.. if there is anything you think i left out or anything you think i should know it would be awsome.
thanks guys

Firstly, you need far more liverock. 55lbs for a 55 gallon tank.

The brown algae is called diatoms and it feedson silicates in the sand and water. This will dissapear once these silicates are used up. Top up with RO water to ensure no more silicates are being added from your tap water ir it becomes almost impossible to remove.

Cycling the tank with damsels was not a good idea. there are far more humane ways these days to mature a system. Also, Damsels are extremely territorial and aggressive. as they grow they would well "own" the tank and no more fish will be permittedin the tank.
The Moray eel will grow large and very fast. Make sure that the tank is escape proof as they can escape through the tiniests of holes in the hood.
Morays also create huge amounts of waste. your filtration system will need to be very efficient to keep the tank healthy. remember that a large fish like this will create more toxins than 3 or 4 smaller fish.

As for your lighting, its fine if you dont want to keep anything other than fish. Tell us whether you intend this to be a fish only sytem or a reef tankwith the types of corals you want so we can advise more accurately.
