My pond is green!

Question
I have a pond about 4'by3'by2'deep. I have had a lot of trouble with it. I live in Lakeland FL
    I put it in about 3 months ago. got the bottom weed I forget the name of them,36  for the bottom. I also have a water Lily, and various shore plants. I have 3 gold fish about 2-4"long, I have been to the local pond place and he says that I should leave it alone so the PH balance and right itself also to create a eco system.It has been 8 weeks now and the water is green with an alge bloom and there is green everywhere! I talked to him again and he says it will get better but the cascade is green and I can't see the bottom!the weeds are coming to the surface and while the new growth is green the rest is a nasty yellow I have a pump but no filter. He said I don't need one. I have the best eco-system there is! I have fish, frogs, polly wogs, and bugs. What mor can I do? I want to start all over but that would be so expensive.
    I have done a 1/4 water change about 4 weeks ago, but it didn't help. I can send a picture if you wish to see it

          HELP!  

Answer
Ok build a biological filter and put pond peat or barley straw in it, I don't know what the PH of the water in Florida is but doing this should keep it at 7.4 or ther abouts. Sometimes Mother Nature needs a helping hand. I think this is a guy that sells pond stuff but doesn't know about ponds. There is very little expense involved. A little green is not bad. The plants are probably suffering root shock. RElax cut off the yellow stay with the green growth it takes a while for the whole biological thing to happen
