I've already posted this in the Informational Sites area, but as most people come here to chat, I decided to post here as well. Koko probably won't like it but I feel that this information is very useful and should be where the majority of traffic flows. If this thread could be pinned so that everyone can see it, I think that it will save a lot of fish dying from 'New Tank Syndrome'. The pH and temperature sections are particularly useful to both novices and experts.

The end of the first paragraph was a bit of a shock:
Statistically, as much as 60% of the fish sold for a new aquarium will die within the first 30 days. 2 out of every 3 new aquarists abandon the hobby within the first year.
