Is very new to me, a fish only person. >Refugiums are for fish only tanks also. The idea is to place Caulerpa in the ref to rob nutrients from the nuisance algae, and is also a beneficial place for copepods and the like to breed and introduce a natural food source.
As far as the book, that question should be placed with Mr. Fenner. There is a forum on the wetwebmedia that has a section for refugiums, and you can also do a search on these at the same site I have had a 3 foot 180 litre marine aquarium for a year or so now and have decided to setup a new 5 foot 400 litre tank (Juwel Rio 400). It is currently maturing and cycling and when the readings are OK, I'm guessing - 3 months or so, I will start to move a little live rock at a time, hermits etc. It will take me some time but best to do it ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
