Howdy Stinger, without seeing any photos of Your set up, I would say to look for and block ANY light leaks into the reservoir, including covering up the Hydrotron pebbles with aluminum foil. Also try to avoid opening up the reservoir a looking too much, every time light gets in, the algae will grow.
