Check the size of your screen vs. the recommendations for feeding. A too large screen tends to spread out the algae and grow dark slimy algae vs. lighter green hairy algae.
If you now have a good roughed up plastic knitting screen - good lighting and hours with the proper size and hours it will work. It takes a while to really get started.
