Re: SAE Problem

Hi Diego,

It's possible 3 SAEs in a sealed bag for almost an hour produced enough CO2
to drop the pH in the bag and cause pH shock when they were released into
your tank. Another possibility is some other water parameter was vastly
different between your tank and the store water, maybe nitrate, since your
level is 0? Fish can go into shock at a sudden and large change in the
nitrate level.

Many people might not agree with me, but I think extended bag-floating does
more harm than good, especially for that long in a sealed bag. I feel a
small temperature difference is not damaging to fish, especially if they go
into warmer water rather than cooler. Many fish in nature live in water
which has noticeably warmer and cooler areas, due to springs or sun-warmed
shallower water and they move through these without apparent stress. Also,
you would have to have a very large bag or a very large temperature
difference to require 40 minutes to equalize the temperature.

I hope your fish are okay when you get home. If  you brought a sample of
your water back to the LFS and compared it with theirs, it might shed some
