tired fustrated and algae

[intarsiabox]

I guess it might just need thinning out a bit then. The stuff under the top layer looks green. The algae absorbs phosphates and pollutants so the only way to permanently get rid rid of it is by taking out some of the algae any way and then repeat the process as it grows back. All those water changes should have removed most of the phosphates that hair algae love so it should start to starve and die off. Are you using RO/DI water?
