Algae

Hi all,

Sorry to see religous types are trying to take over this newsgroup,
but I hope all true ponders will continue to post.

However, I have a pond about ~600 gallons that is 21 months old, built
in July 2003. In 2003 I didn't have any problems , but in 2004 I was
plagued with what I believe was string algea. I tried some chemical
cures, but they didn't really work. Now early 2005 when the
temperatures are still fairly low (UK temps 5 - 10 degrees C) I seem
to have an algea problem developing. I don't really want to go through
the problems I had last year so I'm considering 2 options, the first
is UV light and the second is barley straw (where can you buy it in
UK?)

Pond guessitmated (I know there's no such word) to be about 600-700
gallons, 12 green tench and 25 golden rudd. At least I hope as I have
a heron visit several times a week, but I believe the pond is designed
to protect the fish, i.e. no shallow banks and over 3 foot deep in the
middle.

Any suggestions appreciated.

Regards
