The fish seem ok for now, as for somthing poisoning the fish, I don't know what it could be. The only time I go in the tank is to clean it once a week and I have a shower before hand to get an impurities off me. I use windex on the glass but very carefully. The new bucket of salt I started that seems to have been around the time everything started was stored in the garage for a year. Can it go off? It was sealed but maybe gas fume can get in it?
i seem to be getting an increase in cyanobacteria, but it always seems to increase in the summer. I have no green hair algae so far which is unusual. All the emerald crabs I had have died. The only thing left i the salt as far I can tell.
