I'd wipe it good and before you, drain the water out and try and get most of it, UV/micron filtering might help some, but good CO2, ferts, Mg++ etc............more plants etc..........clean filter etc.
I've taken it from tanks, but I've never been able ot keep it unless I messed with the tank and removed most of the plants, and killed the CO2 etc.
Some folks have not been successful at leaving it alone, then cleaning it after 3-4 weeks.
If it's a one time disturbance etc, then it will go away, a few had success, but others not so much.
Some used EM antibiotics and had success, but others have tried it 3-4 x now and failed to get rid of it.
Some simply tweaked their CO2 a bit, others bent the reflector away from the front of the glass etc.
