Normal for 6 weeks. It will pass if you keep on top of your parameters.
Scrub off and suck out what you can.
Bring phosphate into the 0.03-.07ppm range. Keep it there with WC, this will also keep nitrate low, say 2-5ppm. You can GFO down if you need to. You can carbon dose your nitrate down if you need to.
Reduce light unless you have photosynthetic organisms.
Let that mature a bit more, seek absolutely stability across all 7 parameters.
Over time, it will just get better and better.

I would not add any more sand or bacteria right now. Stability is key, and new tanks are struggling to reach that stability. You'll go through several stages of what we call the "uglies." One ugly builds on the next until you get to that sweet algae-free, clean rock, sparkling water stage. Adding new sand or products will set you back. As @Uncle99 said, it will pass. Manually remove what you see, keep your tank chemistry stable (don't chase numbers, just focus on your regular water changes), don't add new stuff right now. Let that mini-reef bake
