Sometime next year(I've said that for awhile now:-)

 And does everyone

They can try it for themselves and then decide for themselves.

I suppose but they sure are very very quiet.
No one does controls and accounts for the other parameters.
If that is done, then they find the same thing I do.

Try it yourself and find out.
Kill your GW with a UV.
Turn off UV.
Add lots of KNO3 and PO4 etc => no algae
Then toss a jobe's stick in there.
Next try just NH4
Then urea
Then a huge slowly built up fish load.

Algae with each.

Yes, but they can float in the air also.

It will not eliminate GW, but it'll keep it from coming back once you get rid of it.

Basically give the plants what they need to grow, don't worry too much about algae.
Worry about the plant's needs.
