VWD said:Make sure You have good flow and test water, I can't remember everything about Your tank, So we need more info, How long had the tank been set up, test results. What color is the algae and so on and on.
Its not dust like its like a brown saran wrap type stuff. Im pretty sure its shedding because it happened so quickly over night and it has been closed lately. It has good water movement as well and all other corals are doing fine. Thanks for the input.seaham358 said:Is it a dust like algae? Could be a diatom bloom.. Toadstools do shed from time to time and will close up for a few days when doing this.
Add anything new to the tank, lr or sand?
