Hello all

[Stingray]

Hi all, my name is John and I've been keeping koi & others for just 2 years with quite some success including breeding shabumkins and comets, no luck yet with the koi.
My question is I've had blanket weed a couple of times and successfully treated it with 'Clover Leaf', problem is I noticed its return some weeks ago and thought it would be ok until the weather warmed enough to treat it again (10c), it really is getting extremely bad now, taking over the pond, the water is only 5c at the moment, would it be worth treating it now or would it have little or no effect due to the low temperature. Is there any way to 'harvest it' until I can treat?. Thanks in advance, John.

Post pics, and give basics on what size pond, filtration, how many fish etc. Those are things everyone gets asked when they have a problem. Fish waste will feed the weeds. I don’t know what that weed it, but pics will help the others to recognize it. And welcome! There are lots of good articles in various forums about a very wide topic of things, including how to get fish to breed, save the fry from predation by other fish, and assorted plant issues.

Definitely share the details of your pond - how big, how many gallons, how many fish, what size, type of filtration, how often do you feed, etc. All of these will have a bearing on getting truly helpful answers to your questions.

Generally speaking algae is not considered a problem in and of itself - it's a symptom of something going on in your pond that is causing an excess of nutrients which is feeding the algae growth. Getting enough plants growing in your pond is helpful, as is making sure you are not overstocking your pond or overfeeding the fish that you have.

Killing off the algae with a chemical only produces more nutrients in the water that - you guessed it - feeds more algae growth. Every new pond goes through periods of algae overgrowth - patience is really your best approach.

And yes - you can certainly pull the algae out by hand, especially if it's clogging waterfalls or suffocating plants.

Welcome and yep we need more details ,gallon size ,depth .filter,feeding fish,aerator ,pumps and do you test water .It helps us help you .Water temperature will help us also

I recently read something on pintrest about fireplace/pit ashes "helping" with algae 1 tablespoon per 1k gallons or the sort. look it up before you try. my numbers may be off. but i remember it wont fix it but help.

again research it more

Lol, I’ve learned a lot just in the short time I’ve been here. I do a lot of reading of various articles, looking into issues I have, or am interested in, or that just catch my eye in case I ever encounter it. Like I now know that my sisters pond is too small for all the fish she wants for it, but she doesn’t listen to me. However, she has agreed to give me some of her goldfish when she gets a koi, cause she thinks she has too many. ( she doesn’t yet, but I’d guess she’s right at the cusp of stocking limits)

I would fish it all out with a net to remove the nutrients and change out some of the water. You need to work out why you have such high nutrient levels, you either have to many / to big fish or not enough filtration or your cleaning schedule is not good enough.
Fish (bio-load)
Water volume
Filtration
Cleaning / water changing.
If you have a huge pond with few fish you won't need much filtration or to change water.
Lots of fish in a small pond and you'll need lots of filtration and maintainence.
Its all a balancing act, if that makes sense.
