Well , back in the day, It was learning from locals that were involved, Reading back then was limnited to very onesided way of doing things. We didnt have RR tanks available, so most of us used OF's to use a sump. It was hit and Miss back then, Turf scrubers were the fad then and now called FUge with little changes here and there, Flow rates and all were asking LFS's thier opinion, Back then they had knowledge, Today after reading some of the stuff I wonder if profit is more important then really knowing what your talking about. Forums like this have narrowed the knowledge base considerably, where Newbs can ask questions or search the threads for answers.
Reading books today is like getting news a little to late. most of the books use ideas we already implement because they have been shown and demonstrated on the forums, So IMHO reading anymore a book on the subject is thing of the past. Forums give the most Diverse opinions anywhere. Clubs also have a purpose in helping Newbs not make the same mistakes we did. Just my rant..... Sorry
