Our local water supply changed from using the State Aqueduct to using old well water that hadn't been tapped into in over a year because the pipe that fed most of the county from the aqueduct was damaged and needed repair. It was supposed to last less than a week, ended up lasting over a month. The well water was foul... so the county dumped in (according to the water guy at the city) over 25x the normal strength of chloramines to get the water safe for humans.. well.. it isn't safe for fish. I had a chloramine block in my RO/DI but the water guy told me with the levels as high as they were, a new chloramine filter would be spent in less than 20 gallons. I just learned about this on Monday when I called the city to ask what was going on because it was never announced on the news or in any local paper. So dummy me, started seeing corals dying, and first thought is "do more water changes".. and the next day when things are looking worse, I again, did another large water change.. so I was just killing my corals faster by doing water changes and wasting a box of 200G worth of salt in less than 2 weeks. This was the city just north of the one I am in I talked to (the one I work in), and the city I am in has its own separate wells that is always in use, but according to the water guy the city I am in also raised their chloramine levels around the same time, although not the such an extreme.
Even Guillo1's 300G solar lit tank is doing exactly the same thing as mine, all his corals are dying as well, but he didn't do a water change in the month the well water was in use, only used the water for top offs, and it is still killing his corals.
