It was 2:30am and I just got home and I had a 5g bucket full of aged saltwater waiting for me to do a waterchange for my 30g. I would have waited till morning but I had to leave the house early and I wouldn't be back for several days. I went ahead and did the water change while half asleep and stood back to admire the tank. Then it dawned on me... I did't check the salinity of the new water! I grabbed the hydrometer and instead of 1.023 it read 1.027. I pulled some water out and diluted the water back down to 1.023 luckly on the first try. I hope nothing bad happens to the coral and fishies!
