Hello, I just found this great community and am looking forward to reading more of your great comments.
We have an established tank, it's about 3 years old. Yesterday when my husband came home from work, he found that all of our fish had died. The night before they were fine, i was watching them for quite a while. That morning my husband checked them (and the water level) and everything was fine. We just don't know what happened. I checked the water conditions, and even with the fish dying in it, the only things that were off was that the ph
was 8.6 and calcium was 600ppm. We try to keep the ph
at 8.3 and the calcium at around 460ppm's. The only thing that has changed recently is we put in a new ro
filter, but we have checked it several times and the water tests fine.
We are just at a loss, we had about 9 fish in there, with some of the tangs pretty good size. We had 4 tangs, 1 clown, 2 anthais, 1 damsel, 1 golden hamlet. None of the corals are affected and neither are the snails and crabs, they all seem fine. We have been doing water changes about weekly for a while to try to fight nitrates, which are not out of the world but higher than we would like.
Does anyone have any idea what we could have done wrong. We are going to try again and don't want to make the same mistake again.
Thank you and look forward to joining your community,
