I've been told I can use grass carp, copper sulfate, and diuron
I've also heard the carp won't do a good job but Id prefer to use the carp. is this Filamentous algae and can I use something besides chemicals like carp to clean it?

start your research here

If it is FA tilapia will eat it... get in touch with Rainman , he provides this service
Also welcome to the forum

I added 30# of tilapia for my FA. They are working on it as we speak. The mats moved away from levee yesterday, and I would say they have cleared at least 30% of my FA on the bottom. When I say cleared...I mean you can see the colors of the rocks now...its really amazing. I'm going to guesstimate by mid to end of June my mats will be gone, and the bottom will be MUCH nicer. It may be more, but I'm being conservative...I have ALOT of FA.

Rainman is awesome to deal with. Met up with him to get these tilapia. He is from your neck of the woods...so that might be good.

Need to post some pics of what you have so the experts can verify it is FA.

By the way...WELCOME!!!! Great place to call home!

Unfortunately tilapia is not legal in MO. I too am battling some and continue to work to keep the nutrients down.
If they were available I would love to see them do their thing to limit the FA naturally.
There are different FA and they get treated differently. The post above is a great source of info and do start there. I had the water net variety last year.

You can always rake it as an alternative method of removal - its not too bad to rake out small sections, I do this to help make a path for my row boat

+1 on what Matzilla said. You can make one pretty cheap. Even just a garden rake with some pool noodles and a rope will work. Wait till the wind blows it into a corner and take off. Remember to get the dried stuff and throw it on the backside of the levee. Put algae rake into search engine or youtube and you'll see what he is talking about.

Custom, Stinks about the tilapia...I have thought about alum...have you tried that? Its supposed to bind the phosphorus then sink to the bottom.

Here is some pictures.

That is not FA. I don't know what it is though..

The first pic lends itself to watermeal or duckweed, but I can't tell...we need a close-up. The second and third pic shows what could also be pollen and such mixed in.

My bet is on duckweed as watermeal is a finer leafed plant.

Web search "duckweed vs watermeal".

Great looking space! Love the seclusion of it.

Thanks! The house is about 30ish yards up hill behind me there.

Yes I have and have been reading some on it. I have not contacted rainman yet to get his thoughts I am dragging some of mine out like suggested and will continue to do so. It is better than last year (at least so far)
Thanks

Here is some closer Pics.

I'm switching my bet to watermeal. Check out this quick video...

I am not associated with the producer of the video, but It should help you id the stuff.

I’ve got a ton of pollen floating on my missouri pond right now. Your water looks very clear. With the wind we’ve been getting does it all blow down into one end?
I’d give it a week or two and see if it doesn’t go away on its own.

That's not FA, it's watermeal [or duckweed] per QA. It's a pita to manage - check recent posts regarding treatment. There does not exist a biological remedy to my knowledge - either contact [Clipper or Reward plus surfactant] or systemic herbicide [fluridone].

Well, I didn’t look at your “closer pics”. It’s sure not pollen. We have a white film all over the surface at our pond. It blows back and forth with the wind. When I looked at the first pics, I thought it might be similar. I’ve had a bit of duck weed, and a bit of FA. What you have doesn’t look like either of those.

It blows to wherever the will blow it but it does stay year-round until late fall early winter

It pretty much means you have a high nutrient pond. I have seen goldfish gobble the stuff down, but you would have to trade one problem with perhaps a worse one.

A surface skimming pump and filter running 24/7 may knock it back some, but you may need to approach this with a much larger process in mind to really get a handle on it.

First you will need to address the nutrient issue by getting your water tested, and then trying to address any issues this shows. If the phosphorous is high, perhaps an Alum treatment would help get a leg up on it by tying up the phosphorous.

Then hit the pond with fluridone, which pretty much nukes everything of more complex plant life in the water. If the nutrient problem has not been addressed, then you will have that nice FA to deal with after competing plants are gone, and no Tilapia to convert it from ugly to meat. An option after fluridone does its job is to stock some grass carp that will be pretty hungry until plants start showing up again, but then will nip most of the plants in the bud before they take over. Only stock a small amount of GC at first, and only add the bare minimum to maintain.

It is a possible plan, and I hope others will correct me where I goofed or if there are better options. It is not an easy nut to crack, and could get expensive.

If you have the cash, you can always renovate to get the nutrients out, but that can be a big job lasting a year or more. It is also a "cheater" method and a change to expand your pond and add features to improve the fishery.

GC should be stocked as a reactive management measure, not proactive. Stocking GC in a pond devoid of vegetation could cause new problems: perpetual turbidity as they root around in search of forage. I have not heard of GC controlling watermeal or duckweed in any scenario.

Per previous post: There does not exist a biological remedy to my knowledge - either contact [Clipper or Reward plus surfactant] or systemic herbicide [fluridone].

Thanks Teehjeah. I have seen goldfish eat duckweed sparingly in my small pond garden, but that is quite a different ecosystem than a natural pond.

I know nothing about goldfish in a pond other than they can become a management issue...and they can attain pretty significant size. GC may graze duckweed or watermeal but it multiplies so fast they cannot keep up. No such thing as a manageable amount of duckweed sadly...
