Story here is fluval 6 gallon edge been running great for 3 months shown by before pic. I am usually not overly careful with water changes as far as temp and I just hand mix up a gallon at a time check salinity and slowly add it to hang on filter in the back. I recently bought some test kits and noticed my calcium was low which everyone says is common with instant ocean so I got some reef crystals. Did one water change and everything was fine. A week later did some tank maintenance, basic glass cleaning moved a few rocks slightly and another 1 gal change and now every coral except the xenia is really unhappy for going on a week now. At first I checked the water and all parameters seemed fine. The only thing that I changed was the salt. I feel I have fell victim to parameter chasing and swung the numbers to much with the reef crystals and only being a 6 gallon. Setup is fluval nano light, aquaclear hang on filter with sponge chemipure blue pack and bio balls, stock is two clowns, 3 hermit crab and a blood shrimp. 2 hammers, some mushrooms, gsp, xenia and a gonipora frag everything was so happy up until now.
