Awesome! There is quite a bit at the moment... I will try getting to it tomorrow.Just with your water changes will be fine but it can grow really quick, it will take a while and you will think what is going on and then all of a sudden it just stops because the silicates have come out of the sand and used by the algae and removed by water changes.
I'd recommend turning your filter off while you do it and try to syphon out any that scrapes into the water column.

I really hope the algae comes and goes quickly... I really don't want to deal with it for too long
