When I was cleaning the algae off the glass with the scraper I brushed into a piece of rock and it made it real white. Is that harmful? Can I use a BBQ brush to gently wipe the algae off the rocks?
The only coral in the tank are two small (approx 2 inch wide pieces of 1 - 1/2 inch high) fingers. They stick straight up and completely covered in the algae.
