Algae can be caused from several things. let try to go over some of them.
First algae need 2 things to grow, one is light and the second is food.
Overfeeding your fish is usually the main cause, or not doing enough water changes.
Lighting is also a cause, but in a reef you need alot of light. You do not say how many watts of light you have or how long you keep them on. The amount of light you need depends on the coral you keep. Soft corals or even lps do not need as much light as sps corals do.
Another thing that is overlooked is water flow, to little water flow(dead spots) will let detrtus settle, and this will cause algae.
First try adding another powerhead or 2 make sure there is plenty of circulation. Second feed sparingly, feed only what they consume in a minute or two. Vacuum all uneaten food after. Third make sure you have a good cleanup crew. Hermit crabs, Snails etc. In a 55 gal tank you should have atleast 15-20 hermits, and 10- 15 snails. The last is doing your water changes, you should be doing atleast 10 - 20 gals every 2 weeks.
You can increase that to every week untill it clears up. Let me know how this works.
