Welcome Walleyeax,

At first glance it does look like there are 2 types of Algae there maybe?? The under water stuff looks a LOT like Chara I had this myself when I first bought my property. Almost looks like a big green carpet under the water it gets so thick. It will sometimes come to the surface if water in pond get low enough.

At this point it is grown so like your said killing it off may not be so easy at this point. Raking some of it out if you want can be done but it is a chore. What's amazing is how heavy it is when it's wet and then when its dry it's like tumble weed.

Here is the deal though. You can rake all you want it wont help for the next spring. It will still come back. So if you don't really need the pond for anything right now I would let the chara go for this year. Come up with a plan for spring on how to somewhat control it.

Aquashade works good for me to help slow it down.

Cutrine Plus granules work real good on it if you use it at the right time in late spring. If you can use a chemical that is.

Not sure how big that pond is but if you can use them Grass Carp will eat it as well. I have 5 in my pond and they slowly put in a dent in it along with my treating it once in a while they keep up.

Lots to read out here on the subject take time to read, read, read!

Depending on size of pond and if you can have them / get them I would put a few grass carp in there. I would say about 8 grass carp per acre on the low side. So if your pond is a half acre put in 4. You wont see a benefit to it this year but next year you should as they eat the new growth coming up.

Like I said lots of options so read first ask first do later!! lol

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
