A refugium of adequate size would solve your problem, even if you had to set a spare tank in the floor for a few months. They can set beside, above, or below your tank, and, lit 24/7, will outcompete tank algae for nutrients [phosphate, some nitrate] and kill it off. No more scraping, no more scrubbing. You can run one in the cheapest possible tank of about 20 gallons. RUn a closed loop either to your sump or display.
