Algae Control

[Lawrence]

hey i didnt know where to ask this question but the only place i could think of was tropical fish forums
a few weeks ago i had problems with algae control in my pond, and now there is no more algae, however my neighbor still has algae.
i have goldfish (15) in my pond and my neighbor has no goldfish. my question is that, do goldfish help control algae.
i have read on a site that nitrifying bacteria 'starve' the algae causing it to die off. so basically this all revolves around cycling...is this correct?
if not how come my pond has no more algae and my neighbor still has

here is a picture of the type of algae-

Does your neighbour have filters in her pond?

goldfish will do nothing towards algae...ammonia, light and unstable CO2 and also lack of circulation are main algae triggers.

the neighbor does have a fountain in the pond and i do not have one, so basically the nieghbor as more water circulation than i do. but how come the neighbor still has algae,and i dont think they have a filter in the pond, neither to i.
and does anyone know a method of how to get rid of the algae,or a produt that will help
