@ ceg4048: I used spraybar at the first time I know aquascape. BGA always appear on the deadspot, so I decide not to use it anymore. Since I use single outlet, BGA never appears.
If you've never used single output or lilypipe then how can you be so sure that they are ineffective?
I did not say that I've never used single point pipe outlets. In fact, I've used them for years and I've compared their performance with spraybars. So I know exactly how the single point configuration works. You are the one who said that you never used spraybars. This was the opening statement of your post==>

I never use spraybar on all my canister, only use single output
Now you say that actually you have used spraybars before and that you got BGA. Was the spraybar the only thing that changed? How did you mount the bars? As i said, if you use the bars incorrectly you will have poor performance.There are thousands of people who get BGA in their tanks. Some are using spraybars and some are using single point.
Likewise, there are thousands of people who
don't get BGA. Some of these people are using spraybars and others are using single point. So, just using spraybars, or just using single point does not really tell you the whole story. Your choice of configuration is only one factor in growth performance. There are many other factors. As stated earlier If you have strong enough movement then it won't really matter that much.

If spraybar is the effective way to get best circulation, why amano never use spraybar..??
I would only be able to guess at the reasons because I cannot read his mind. Based on the comments from other excellent aquascapers, it seems that they typically do not like the look of a proper spraybar installation. Visually and aesthetically, the spraybar is not the best. To make matters worse, manufactures produce spraybar designs almost as an afterthought, with very ugly materials and colors. The lilypipe configuration is so much more elegant, especially when executing a minimalist aqauscape. It's just not very artistic to stick a long green pole on the back of the tank.
Just because there is a best way of doing something it does not mean that people will automatically do it. If there is a less effective way of doing something, and if that way satisfies some other objective then that is what the person might do.
When a beginner asks for advice on how to execute a concept, I formulate a response based on best practice, most efficient, least expensive and most effective. It is not my intent at that point to consider what Amano does, because that kind of response does not help the beginner. There are lots of things that Amano does or or lots of products that he uses that are completely irrelevant to the way that some people live or to the way that some run their tanks. It is a very foolish policy to do something just because Amano does it, or just because I do it, or because you do it. There are some things I do that I would not suggest to others because they do not live the way I do. There must be a context when describing the way that someone does something, and it must be clear what the advantages are and what the disadvantages are. It is a much better policy to understand the science of a product or technique and to learn to apply that technology to your particular application in a way that satisfies ALL you goals.
