Green water is very easy(easiest) to get rid of and does no harm to the
plants(except for blocking the light etc). It is also easy to induce. I do
not believe it's needed in any way though to prevent other algae. They  just
need more plants from the start. Algae, GW, will do if you don't have enough
plants. That is what's happening. You can use plants in the exact same way.
Many folks do that every time also. Most folks try to avoid all types of
algae as a goal and use plants. GW is not a particularly troublesome kind
though and fits the bill sometimes. Personally, I try to use plants but it's
not a big issue if GW happens either. At home I have the control to pick
which method I want. Problems with maintaining a tank from a distance can
cause some to give up and just let the algae run it's course. GW does not
prevent other types from appearing though, although they do compete, but so
do plants. Plants are still quite needed and more helps in all cases.

Well it prevents other harder to deal with algae from moving in and GW likes
low nutrient (oligotrophic) along with diatoms(brown algae). Otto's will eat
the browns like no tomorrow. Shrimps will eat most of the other types of

I'm sure his customers are not too thrilled when it happens though. But it
does go away and is not bad afterwards:) Just some extra work for one-2
visits. Main thing when setting up a new tank is to get as many plants in
good shape as you can. this is not easy and folks always underestimate how
much plant mass they need for a new tank.

I do. Problem is...some fish like them for food!
