Tank transfer didn't go well

Cant see salt mix being a problem. Lots of times, I have mixed a major cganhe for only a couple hrs. no problem. Most of my tank changes have been like yours. Part old water and part new water. Have not done sand changes in awile but when we moved Mike,s from his 120 to his 150, we moved most of his sandbed, which he did rinse well prior to putting it in the new tank. And we left the sand over night before moving more, so not sure if that helped or not.

A few years back, the one time I did have a problem and lost many sps and clams on a tank move, was an alkalinity issue with then new water. How many of us measure the alk. of the new water? For sure back then I never. Do now though.

Other than that I,m at a loss.

Thanks Doug.

I thought alk right away too but I did actually test my new water and the old water. The new water was 8 and the old water 7ish, maybe closer to 7.5 (I am using Elos and it started to change colors inbetween drops kind of). So it was a little different but once I mixed the new water in, I tested and got 7.5. A day and a half later and I am still getting 7.5, so alk has stayed steady.

I guess I should mention, I have a lot of sps and even though I lost some of the bigger colonies, its maybe only about 15% loss. The tank doesn't look bare or anything. Infact it looks decent and now has plenty of room to grow. The problem is I lost some of my favorites

I have done a few tank transfers in my day (moved a lot), but the only time I ever had anything like this happen (and it was exactly like this) was the only time I reused the sand, so naturally I blame the sand. It was a total and complete tank meltdown within a few days of moving, beginning immediately after setting up the new tank. Sorry to hear about your losses, I feel for you.

Thanks. Well I hope this doesn't continue and become a total meltdown. Next time I think I would just skip using the old sand all together.

EDIT: Actually the latest acro that I thought was receding from a few tips was one that had fallen into another acro yesterday, so I think its fine and just damaged from that.

The lights are on now and all the remaining corals look really great actually. No signs of any new stress. The birdsnest has not receded anymore but I think I will frag it tonight to make sure it doesn't spread.

No ideas but hope things come back

Well no new casualties today. The birdsnest seems to have stopped receding but I have a funny feeling its a goner. I have been told though that birdsnest can be tough with moving tanks.

Everything that died seemed to die by yesterday morning, so perhaps thats it. I hope.

There was one acro I though was going but then I remembered it had lost a battle when falling into another acro, so I think its fine. Looks fine anyways.

All in all, if that it for deaths, I would have to say it DID go ok. Fish are fine. Most corals look good or even better. The tank overall looks much, much better than my old tank. Its just that much bigger and was very nice to aquascape 30" from front to back.
