Is sand better than gravel?

There are a few factors to consider when determining which substrate is best for a planted tank. The main factors to consider are water holding capacity, drainage, and filtration.

Water holding capacity is determined by the weight of water that can be held by the substrate. Sand has a higher water holding capacity than gravel.

This is because sand is made up of smaller particles that hold more water than larger gravel particles.

Drainage is important because it determines how easily water can be removed from the substrate. Sand has a superior drainage ability than gravel because the sand particles are smaller and more closely packed.

This means that water can flow through the sand more easily, which is important for keeping the substrate clean and free of debris.

Filtering is also important. Gravel can block the flow of water and substrate particles, which can lead to algae growth and a dirty tank.

Sand does not block the flow of water and substrate particles, which means that it is better for filtration.

Summary

Koi fish do not need gravel, but they do benefit from it. Gravel provides a place for beneficial bacteria to grow, which helps keep the water clean and healthy for the koi.

The gravel also provides a place for the koi to dig and explore, which can help them stay active and healthy.
