If the Algea is not about to kill the coral in your tank your better try to find where they came
eliminate the source of the problem and then the algae will go by them self

Cylcling and new tank,to much feed,to much additive,low calcium and alkalinity,defective or
no R/O check your top off TDS,copper ting inside the tank are most of the time the cause

Good carbon,poly fylter,water change (assuming your water have very low TDS), heavy skimming,
put a diatom filter will greatly help to if you have one, if you dont, and have a sump buy 2 swiming pool cartrige and put on in the intake pump of your sump and clean (Javel) it every other day rotating whit the other one. are most of the time the good medication

Tell us more about your tank and 99% of the time we will fix the problemm chemical free

Good luck!
