Hey everyone I had my fluval 32.5 tank for almost a year up and running out of no where all my fish besides my spotted goby fire shrimp snells star fish and hermit crabs. So I I made a decision to upgrade to a 65 gallon it’s up and running since March 12021. I added two clown fish a half back angel fish pistol shrimp. Within 3 days one of my clown fish and angel where died. The only thing that is high is my calcium. My levels are 1.021 salinity calcium is 520. Phosphate are 0.25. Nitrate are 20ppm
