Doing a waterchange yesterday.Forgot how cold its been and without checking temp of the fresh saltwater to be added,I changed out my 5 gallons.Glanced at the tank temp and it was 76.Normally it runs around 81 so its got me a little worried because acro's are real sensitive to temp spikes but not sure how they'll respond to the cooler water.Its back up to normal now,but wish me luck.
