I set up my aquarium about a year and a half ago everything was doing good until I moved where I moved to the building was hotter and I noticed that I had a lot more evaporation so I will top off the tank with salt water not realizing that the water evaporates but not salt I was wondering why I was getting salt spikes until I was talking to somebody at my LFSO who then told me what I was doing wrong but by this time I had lost all my coral totalling about $2000 Canadian so if you’re new to the hobby please do not make the same mistake I did
