Bryopsis was actually pretty easy for me to get rid of. First solve your phosphate problem, here is how:

Second, buy a few jugs of Kent Tech M and use them to keep your Magnesium up at 1500ppm until the bryopsis goes away. Thats what worked for me anyways.

I've also used natural control for aptasia and any majano that I've seen have peeled easily off of the hard surface that they were on. A friend of mine shared a trick with me that worked well for him. While cooking some live rock he shined a narrow light onto a spot in the tub where he was keeping his rock. Slowly all of the aptasia and/or majano migrated to the spot of light where he was then able to remove them.
