2nd year ponder help needed

I am a 2nd year ponder. Last year I had a 6 foot round about 3 feet deep
pond. I simply fell in love with the whole thing. I did fight the string
algae all year but overall I loved it. I have six gold fish and three Koi
and about 15 little minnows that my kids got out of the local creek. My pump
is a 1200 gpm. The waterfall is about six feet up.

I loved the pond thing so mush that I put in another pond this year. It
connects with the first pond and is about 4 X 8 X 4 feet. I did not ad any
fish in it and left the old fish in the first pond. All of my lilies are
coming back strong. Even the tropical ones, they don't look as strong and
as big as the others. I got some barley straw early this year and haven't
had any problem with algae this year. The pond got crystal clear and stayed
that way for two or three weeks. Then it turned, I can still see the bottom
but it has a greenish tint, and just a little dead algae floating on top
every day. Nothing I can't skim off in 2 to 3 minutes. It all looks a
little stagnant and I also now have some sick fish. (See other massage Sick
fish). I also added a bog filter about 5 X 2 X 1.5 feet. I think that's all
the info you will need. So before I keep rambling on here are my questions:



Is my pump to small?

Is the decaying barley straw making my fish sick or responsible for the
murky water?

OH one more thing! About every other day I fish out a half gallon of frog
eggs. Now I don't mind some frogs but this is too much. Anyway I can get
rid of the frogs? Thanks for your help.
