In regards to dissa gree with hobyists or other sceintific type, well
both. I ouwld have to go back ad look and read the books to check for
diferences, but one thing and I will not say it was Shimek, that
stated it or the other person, but the charts on average reef temps
varied, as did specifics on salt water contents and the ideal SG and
other parameters and temps to keep a reef tank at.....

Interesting... :-)
I think you refer to the article "What are Natural Reef Salinities
and Temperatures.Really..and Does It Matter?"
Is there incorrect data about reef temperatures/salnity he quoted ?
What could be the disagreement if facts are correct ? Just curious...
Unfortunatelly, I have no chance to do measurement of sea temps
and salnity so I need to rely on what is in scientific papers...
If his quotations are false, than what is the truth about temps on the reefs?

One recomends undersand filters or plenums and deep sand beds
where shimek stated no deep sand beds with or without plenum IIRC

Shimek is recomending sand beds. I would like to know a different
point of view on this subject from a different marine zoologist...
Do you know a scientist who is opposite to deep sand beds ?

Tea, the book is bound to be cheaper. I picked up a copy (softcover)
of his titled.POcket Expert Guide to Marine Inverts......for 50 cents

Do you suggest this book is equal in value to the course announced ?
I am not sure you if you can compare the value of a book to active
participation in an online course but if that book was so good it was
probably worth every penny... ;-)
