I have blinds across the window. To give you an idea, my currently empty aquarium sits within 6 inches of the window and about two and a half feet away from the doors. Another problem I have concidered with its current location as that my AC
/dehumidifier is mounted on the wall about two feet above my aquarium. Due to the humidity here, it is neccessary to run dehumidifiers to keep the mold from growing. I'm not sure how much this would be a factor either. I might move it to a different wall. The window is easy to cover, but the sliding doors are open quite often making me wonder how bad the sunlight would be.
Also, I live rock-throwing distance from the beach. I am thinking that using my freshwater filters (2 x 100 gallon pumps) with fresh rocks out of the ocean instead of filteration media would make the water suitable for a clean, constant ocean-current habitat inside my aquarium. I plan to take sea floor sand, ocean water and a few rocks for inside the aquarium. Any pointers?
