when you say slowly. can you explain this process. I dont want to mess anything up.
When you do your water changes, just take out 3 or 4 and eventually they'll all be out. Also, for the stuff building up in your sump you can use a gravel vac to suck it out during water changes. Oh, and you need to have a light over your macro algae so that it will grow, it's basically a plant.
