So just an update the algae is still growing but much slower. Once it got fairly thick on the sand bed I scooped most of it out. It does still grow back but not nearly as quickly. The blackout period has claimed 4 of my corals but luckily none of my favorites. I have some bacteria coming tomorrow as well as a filter sock holder because my sump did not have a place for one. Hopefully that will help with removing any algae that I mix up. I am debating if I want to remove all of the sand that I can and then add new live sand but we will cross that bridge if it doesn't clear up.
