I just bought a 55 gallon tank(20 inch high), and noticed the Jack Dempsey poop is just sitting on the sand. The poop is all on the left side of tank. The filter HOB is on the right side of tank. The poop is visually noticeable, since the sand is light and the poop is dark color. I have a fluval 70 filter HOB. Should I buy a powerhead to try to get the poop and uneaten food to flow up to the filter? Should I just keep the poop on the sand and let the nitrogen process take its course? Should I gravel clean the sand once a week? I dont want to do this,,,too much work.
