So i was doing my pwc over the weekend! Had water mixed up sitting for over 24 hours just doing the norm. Took my digital thermometer out of the water powerhead and heaterout... started to remove water from dt tan took out about 20 rather then my normal 10 nitrates were showing 20 anyhow tiger the point i lost my royal gramma due to my my digital heater being set for air temp and actuall heat being 86 degrees. By the time o notced i was already half way done took the plunge add cold tap to cool it down but forgot to add more salt... so not only did i lose a fish but salenity is ar 1.22 and iknow my poor corals have to stick it out till i can raise it safely...
