We have the same issue, we have Best Sand the ridiculously expensive white stuff. If we can't rake it regularly it will develop algae. This winter/early spring we edged and then used hoes to rake deep furrows into them. In an attempt to sort of rotate the sand from top to bottom and air it out. It helped quite a bit, we can't do anything mechanical due to having fabric liners and bunkers designed to be smaller, to almost force a hand raking. It also helped when we had huge wind come through a few ago, sand settled into the furrows rather than blowing out. Look to actually be fully staffed this year so we will be able to rake bunkers daily to eliminate the problem.
