I'm new to your site and to the hobby. Set up 75 gallon tank Saturday before Christmas and has been doing very well until recently. Started with live rock, a variety of snails and hermit crabs. Later I added Tomato Clowns. I have been doing great job of testing water quality. My pet store suggested I raise p.h. from 7.8 to approximately 8.3. It was suggested to use Marine Buffer by Seachem. The p.h. would still bounce back to 7.8 until I kept adding buffer according to instructions for several weeks until the p.h. leveled to between 8.2 to 8.4. The Clown Fish have always done fine and still are. However, all snails and hermit crabs have died as well as several new batches of snails and hermit crabs ever since. I was told to stop using the buffer which I have not used for weeks. All water quality test including salinity appear to be optimum. What does anyone out there think what is happening and what should i do?
