Dead spots in the aquarium are places where the water flow is so low that detritus accumulates. These buildups of waste and debris can be huge sources of organic decay that release algae-fueling nitrate and phosphate, and if the water flow isn’t sufficient to remove these substances, the water quality can quickly degrade. Since eliminating every single dead spot in the aquarium is probably next to impossible without causing sandstorms and other issues, manual removal of these piles of debris is a must. Simply siphon out the low flow zone as needed.
