I base my opinion on this link

It is a study of Cheato, but it is mentioned that most marine algae behave in a similar manner.
I can only offer my experiences with this as "proof", but due to a lack of outlets I run my lights 24/7. During the scrubbers intitial breakin period of 4-5 weeks the algae grew like crazy and I got enormous amounts of stringy growth on the screen.

Now after almost 2 years of the same 24/7 schedule the results are obvious. The algae is very thin and weak. Also there has been an increase in DT algae in certain areas. IMHO this is a very important part of the ATS that really needs to be followed correctly for long term success.
