Here is an email I got from Aquahub.
"Hi There,
Was reading your comments on a thread at the end of Jan. You actually quoted my
website - aquahub.com.
Couple things - you mention putting together a talk on electrical safety with
aquariums. If there is anything I can do to help you, please let me know.
Also, appreciate you referencing our piece on spiking voltage and using relays
with float switches. Do you have any comments or suggestions on that content?
Any comments or suggestions in general about the information on our site?
Thanks very much,
Patrick, Aquahub.com"
