Pond algae

Hi all, had to do some careful maintenance on the fish pond this morning (it being wildlife season) as a bright, lime-green slime appeared over 2 thirds of the surface for the 2nd time in 6 weeks, in fact as soon as we had a little bit of sun (again).
I'm used to dealing with blanketweed and duckweed but this cloudy, hard to catch slime, is new to me/the pond.
I'm guessing it's a form of algae and this means the nutrients are too high. I replaced the uv bulb on our kit 6 weeks ago and hoped this would have stopped it returning.
Any tips and/or a name for the algae would be appreciated, to help me control it, cheers.

The presence of algae is pretty normal at this time of year 8000wildflowers. Algae gets a head start on the higher plants by taking advantage of a greater degree of sunlight and raised water temperatures. However once your 'higher' plants catch up they will take over and deprive the algae of nutrients
It means the nutrient and or dissolved oxygen- carbon ratio has changed.
You got fish in there?
Thanks Fishy.
Yes Darren we had c20 fish new in last year, reduced to c15, possibly 10, by the heron recently. This is the first year we've managed to keep more than a few due to the heron clearing it out so fast, so there may be more fish poo than normal. Maybe not for long tho', the latest heron seems to get around the miles of fishing wire...
But our pond system can cope with more than 20 fish in case they breed (sadly not yet).
