I have lost two shrimp and a spinny blue lobster in two days. the lobster has been "dying" the entire time. My water parameters are all fine but my waste levels are high. I tested my levels with my FasTest Kit and they were all normal, I took it to the local fish store for a second opinion and sure enough they were off. All they told me was that my waste levels are high. I assume that means nitrate and nitites. I have done two 25% water changes since that news at 10:30 this morning. PLEASE HELP! Thanks! Any advice would help i don't really trust my local fish store.
