Yesterday I mixed a fresh batch of saltwater. 30 gallons in a brute can. I have my sump and mixing station in an unfinished basement. I had every intention of doing a water change last night. I got involved watching the football games and put it off until tonight. I get home from work and am getting everything ready, I got to check the salinity of my fresh batch of saltwater and I found a dead mouse floating in it. Stupid me left the lid off. I pondered using it anyway. I hate to waste the salt. But decided against it. Dumped the container and am now mixing a fresh batch. The water change will have to wait one more day. Anyone else ever found anything interesting in their mixing stations?
