Yesterday, I was a bit unhappy to learn that the tank is still reading ammonia. The algae was also back. So, I wiped the tank clean again and began catching algae with a piece of filter cloth. In addition, I added some bacteria and another 10 pounds of live sand. I also hired a cleaning crew to assist with the algae growth. The crew consists of 3 hermit crabs about the size of a penny. I look forward to testing the water again in 24 hours and seeing the nitrification process jump started.
