Kirk Posted March 21, 2021 Share Posted March 21, 2021 I have a 150 gallon tank. Water is soft 3-5. I want to keep Nerites maybe other snails but the fish I have are in their comfort zone. What can I do to help them survive? If I add a wonder shell or cuttle bone is that going to mess with my water hardness to a point my fish are stressed? I really don’t know how much these items effect the water the fish are in. Link to comment Share on other sites More sharing options...
