The soil help to lower the ph in the water which the shrimp prefer and for better molt. Shrimp can die from difficult molting due to higher ph. Although higher ph do make the shell look good but it will cause the shell becoming too hard to molt thus causes death.thomeski;4808641; said:Fish in there are only temporary i need to rehome em after cycle is done.
