Re: [APD] Aquatic-Plants Digest, Vol 25, Issue 50

It looks to me like you can enjoy this hobby in many different ways.  
If you like tinkering, "inventing", making your own equipment, you can 
enjoy that activity, as I do.  If you enjoy aquascaping, making the 
artistically "perfect" arrangement of plants, rocks, wood and fish, you 
can enjoy doing it that way.  And, if you have a scientific bent, and 
enjoy research, you can buy lots of meters, gages, test kits, etc. and 
enjoy that part.  I don't see any of those approaches being superior, 
but just different ways of finding enjoyment in a hobby.  Tom Barr is 
unique in having many years of experience, both at his job and at this 
hobby, and, as a result, offers information that I haven't seen 
anywhere else.  His approach may not appeal to everyone, and it 
doesn't, in fact, but the information he provides is certainly very 
helpful to everyone.  Now, as to light levels, I really would like to 
see more empirical data on the effect of light on plant health and 
growth, and an improvement to the watts per gallon standard would be 
very interesting indeed.  (Not that I would necessarily change anything 
as a result.)
