I made a aquarium with natural substrate method with the garden soil covered by the sand kept in the natural sunlight ,The fishes and the plants are growing well. The problem is ,more amount of fish wastes are depositing over the surface of the sand and its getting disturbed by the fishes movements and the water turns cloudy and greenish. Soon after slowly the plants are started dying .Even the fishes count is also less and there is 2 nerite snails also. Need a solution for this.
If the nitrogen cycle is set, then this problem will not occur. One shortcut to manage waste is to introduce some shrimps. Waste can be from fish or from food itself. Can you let me know what you are feeding, how much and what frequency.
I would advice switching to dry blood worms. It is near natural than pellets. Also reduce the feed for some days. Run a air stone for a few days, or best to use a sponge filter. Once the tank is set, you can use filtration or air stone as needed.
I hope this helps.
You are very welcome!
