Cyclic sedimentation filter of turtle fish mixed culture imitating natural original ecology

At present, there are two grass turtles, two southern stone turtles, two crucian carp, one goldfish, three loaches, three large field snails, and countless black shrimp in the fishpond.

Volcanic rocks of different sizes are placed in the pond to hide and breed black shrimps. The fish pond uses a small pump to pump water circularly and purify the water quality through the sedimentation filter. The turtle pond uses a small air pump to pump oxygen to increase the oxygen content in the water.

The filter tank and fish pond are all made of volcanic rocks for sedimentation filtration and bacterial culture. The filter tank is used to plant three kinds of plants, water celery, water calamus and stone calamus. The fish pond is used to float and plant stone calamus with foam board, which is also a small platform for turtles. Turtles and fish will not bite the leaves of stone calamus.
