So the install day came for our basement floor install. We are renovating and had the carpet torn out and laminate installed.
I had offers of babysit help (and I appreciate it

)but since I had an empty 40G sitting around I figured I would set that up as a temp tank.
On Thursday I transferred my fish and corals into the temp tank using existing tank water and kept it moving with a couple koralias and a stealth heater to maintain temp. I also put on a coralife PC strip light I had just for the short term. The live rock went into rubbermaid garbage cans with powerheads and heaters.
The installers came Friday and did the job in one day ending around 6:00. I checked in on the temp tank and everything seemed fine so I decided that I would wait until Saturday to get everything set bck up.
That is where my mistake was
Saturday morning after breakfast and coffee went down to look at the temp tank and smelled the death before I saw it.
The death count is at:
6 SPS Colonies
1 Cleaner Shrimp
5 Chromis
1 Hippo Tang
1 Sixline

I had this guy for almost 4 years
2 Aussie Black clowns
The Survivors:
All zoos rics and mushrooms
Buble Tip Anemone
All my frogspan & trorches
Purple Tang (thank God!! I had him the same length of time as my sixline)
Sand Gobie
1 Chromis
Neon Goby
2 Clams
So I'm still not sure what went wrong.. to me it is surprising that sensitive creatures like the clams and 'nem survived yet there were fish losses.
Anyhow.. just a rant I guess.. I've moved tanks so many times now I thought I had it down to a science.. but I guess you learn something ne everytime.
