How do you deal with fish poop?

While fish poop may not seem like a big deal, it can actually be an environmental and health hazard if not properly handled. Fish poop can contain parasites, bacteria, and toxins that can contaminate water and soil, and can also be harmful to fish and other aquatic creatures.

To properly deal with fish poop, it is important to first understand the different types of fish poop. Fish poop can be made up of three main components: fish excrement, fish scales, and fish skin.

Fish excrement is made up of small feces and urine, and is the most common type of fish poop. Fish scales are small, sharp pieces of fish skin, and can be difficult to remove from water.

Fish skin can also be difficult to remove, and can cause water to become cloudy.

To properly deal with fish poop, it is important to remove all three types of fish poop. Fish excrement can be disposed of by composting, while fish scales and skin can be disposed of by skimming.

Skimming can be done using a net, water filter, or paddlewheel.
