what chemical product did you tried ? For me I tried vibrant (pic below) and it worked very well.
For the live stock i have emerald crab and they are good algae eater and some blenni are good too.
for your aptasia you can go for a filefish its litteraly their job too get rid of it.

Are you referring to the longer stringy hair algae, or the short spongy turf algae? Pic? I have a pincushion urchin that ignored a stubborn patch of turf algae for months. Then one day he decided to go to work. It took about a week to decimate a patch about the size of a playing card. He also does a good job on the hair algae.
