[Killietalk] Acclimation

[kingfishseven <kingfishseven at peoplepc_com>]

Hi All, I just wanted to add to the great discussion in regard to acclimating fish.  When I worked for a wholesaler back in the day, we did an experiement.  It had to do with the drip tubes(airline) and a knot or clamp to control the flow.  Using a Lamott tritration test kit, we found out that dripping water from the good tank water only prolonged the deteriorated conditions in the bags and buckets.  Thus, almost keeping the carbon dioxide and dissolved oxygen constant. While these bags and buckets often had 100 to 300 fish, and sometimes just one fish, we decided to acclimate faster to save the bosses money. We used the splash method from that time forward. The only thing we did was to make sure that the temp was close.  The biggest problem ocurred when we received Hikari Goldfish that were in cold - packed conditions in very little water.  We had to add water quickly since dissolved oxygen decreases with increasing temperature. I have always used the splash method unless I!
  was acclimating sensetive fish. What I do is add a half a cup of prepared water every 3 to 5 minutes until the water volume doubles. Then as Dr. Terciera does, I let the fish in a net, discarding the water after releasing them to the tank.

While we received wild discus at that facility, we did the splash method. It actually seemed to prevent the gill damage that so many fish get when acclimated too slow.
