I started a new 20 gallons fresh water tank. After several weeks I noticed the water looked cloudy. It turned out to be dirty glass on the inside of the tank. I bought a sponge on a plastic stick but it doesn’t budge the film and green algae. What type or brand of sponge would you use instead of the cheap ones? I don’t care for the magnet type. Thanks for any replies.
