Hello, I have a ten gallon nano that has been stable and beautiful for three years. I do a weekly one gallon water change on this tank. I did the water change on tuesday, in a few hours both shrimp and crabs looked bad. They are still alive but barely moving and not eating. All the water parameters, salinity alkalinity, temp and ph check out fine. I even did an amonia and nitrite test to catch maybe a spike but those were zero. All corals and clownfish and snails very happy, business as usual, crabs and shrimps very bad. I figure I must have accidentally poisoned them with something, but I cannot think what, I did the water change exactly as I have been doing it for three years. My question, I did a water change a little while ago and am planning on doing one tomorrow. Is that my best bet, just doing a water change every day til I dilute what ever is in the tank? Am I missing something? Any help would be appreciated. Thanks, Teresa
