I was just wanting to know how do you keep the algae of white reef rocks. They look so good when they're clean, then the algae grows on them and makes them brownish on top. They real rough rocks so I can't really just scrub them. What do you guys think?
I personally prefer the look of algae on my rocks. I liken sterile rocks to plastic plants. Both look unnatural, but I do clean the front and side viewing panels regularly. What do the rocks in the real world look like? If you must, soaking in bleach and then rinsing very thoroughly is about the best I can do for you. I wouldn't worry to much about chemicals, bleach evaporates very quickly. You just have to make sure you rinse it really good and then let it dry.
