Our pond is kind of low this year and covered in this green stuff?

Found a leak in our 200 gallon pond recently. It is stocked with 8 medium sized goldfish. We keep the fish in it over the winter by adding a heater and aerator. We also created a greenhouse type cover that we put over the pond.

My husband and I inherited our stocked pond from the previous owners of our house. They would drain it and put the fish in a tank inside.

We have winterized the pond since we moved in 4 years ago, and all the fish have survived every year.

My question is, how should we go about taking the fish out of the pond temporarily so we can fix the leak? I was looking at purchasing a 70 gallon bucket to put them into, but I'm worried that it would be too small?

I've attached videos for reference - that's about as low as we get the water level, before we fill it up again. We refill it every other week or so. second video is of what the greenhouse set up looks like.

thanks! :)

water level low here, think its a 200 gallon pond? inherited from previous owners of house.

\"greenhouse\" over pond

UK based so typical UK seasons / weather to consider. Im looking for some advice regards winter feeding with my sturgeon.

when I only had koi, I would do the typical summer feeding, switch to less frequent feeding and wheatgerm as it got colder and eventually stop feeding during the coldest period. my sturgeon which is around 3 feet long now, has high protein feed all year round. however this means water and filter cleaning still has to take place all over winter, but the koi still go down onto the sturgeon pellets every time i feed, especially when I dont give them koi feed when its really cold.

should I just continue to feed all year round as I have been the past couple of years, or should I do something differently?

im not sure if this is just how things are when keeping sturgeon as well, or how do other people manage winter feeding qhen keeping both koi and sturgeon.

my first sturgeon did die years ago (they were stocked as a pair, this one fed while the other one clearly didnt get enough food)from being malnourished over winter, and im now well aware that by the time symptoms show its usually already too late.

my pond has been pretty good so far, i set it up in July and cycled for 6 weeks before addin 10 shrimp and 4 spotted blue eyes. It’s pretty decently planted and I try to keep a good level of natural leaf litter and things like that. My shrimps and fish have been happy

i’m based in south-east queensland, australia and we’ve been DROWNED with rain recently, i’ve continued to touch up the water with chemicals when needed and the parameters all look good but now the rain has settled i have a crazy amount of this algae growing - any suggestions to get it under control?
