Hi all,


2 acre lake max depth 18' very clear water. visibilty 8' Great fish population. No feeding.

First have I correctly identified this as FA?

FA is currently thick from shore to depth of approx 8'

I have applied Cutrine Plus 2x this year. It turns the FA brown that is in water less than 2' The FA in water greater than 2' has stayed green and continued to grow.

This weekend I raked as much out as I could reach. I am happy with results and think I got most of it out. What should I do to inhibit future growth/ limit it to where I want it.

Thanks!

To this uneducated eye it looks like Chara. Cutrine is for algae, which this is, but it's hard to control this late in the year. I first thought it was Sago, but took a closer look after I typed my reply.

Are you using liquid or granular?

Liquid... My first application was mid March during the warm up as it was growing quickly. 2nd app was mid may.

Since Chara grows from the bottom up, I'd try the granules. They'll sink down in the deeper water and get closer to the target. I think that's why the liquid is working closer to shore, but not in deeper water.

After a little reading I believe it is Chara too.... Boy it stinks!!!!! Looks like I may want to leave some of it in there??? It has just gotten soooooo thick in an undesirable area..

Thanks!

Yep it's Chara! The stink is one of it's identifying characteristics. I've fought it for years although it has some redeeming qualities. It will maintain clear water in a pond and it's a great home for invertebrates.

The bad side is it can become quite prolific and when it dies underneath the living plant material it creates a muck layer that continues to feed the living Chara.

It's probably to late to treat it now as thick is it is, and mechanical removal is the only only good option. I doubt you'll kill much of it even with the granular and even if you did you could create some D.O. issues if it's really thick. If you're in northern Indiana by some chance the hard water also makes it more difficult for copper based herbicides to work.

Be aware you will never completely get rid of it by mechanical removal, although is is fairly easily raked out with a good weedrake with the big plastic teeth. Being a type of algae it reproduces by spores and fragmentation so it's there forever. I've even drained and dried ponds only to have it come back.

Other than mechanical removal, two good options are grass carp and a heavy dose of Aquashade early in the year just after ice out. The grass carp may not seem to do much the first year but you have to be patient.

There are downsides to shading a pond so be aware of those before you use that tool.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.

Chara was my first thought, too, and then I saw this post about the smell and knew we had a winner! Cecil's advice is spot on - listen to what he has to say for sure. I have a lot of chara in a very clear and shallow hardwater pond. I was going the tilapia route but it looks like that may be fading as an option this season, so chemicals and manual removal are likely my next move.

Another name for chara is skunkweed. I've cleaned it up in 3 ponds with grass carp.


It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Yeah I agree with Double D here. I have 7 grass carp and my pond weed is all but gone, but I have loads of chara still. I mean looks like carpet under the water in places. Not to sure what to do about that crap???? I thought my GC would control it but, I may have been missled about that I don't know. Maybe they don't like the smell either?? smile

Just give them time. They prefer pondweed but should get on the chara.

DD2 do you have chara issues and if so are you using GC to control it? And how may GC do you have? I fear maybe I will need to add 2 or 3 more for next year.

I don't personally have chara but have stocked GC to control it on several other ponds. I like about 6 or 7 per acre. Of course, that depends on the infestation and how impatient a pond owner is.

I put 7 GC in my pond this last fall. Given they all made it and are still alive. My chara is something else. I mean it looks like I could walk out on it!!! It's about 15 inches or so under the water but it just covered like carpet in about the 3 to 5 foot range. I fear 7 grass carp may not be enough to handle my infestation. I don't need it all gone but dang it man I have more than enough. I was using a normal size beatle spin the other day and when I let it sink it just sat there on the chara it wouldn't even do down into it that's how thick it is.

Sometimes round bodied GC only 9"-10" long are easy and good food for bass 18"-20" long. Is that a possibility? Often pondowners with larger bass buy too small of GC. If the GC are still alive, you may need to help GC remove some (maybe 50%) of the Chara this summer. I don't know how big your pond is and the amount of effort needed remove a decent percent of the Chara. With a good amount of Chara removed by fall, next spring they should do a better job controlling it and you might only need to remove 10%-25%. IMO you want some Chara present (15%-25%) or another submerged plant to compete against Chara. With no competition Chara grows very well in many ponds that are not turbid, fertilized or have good algae blooms.

Hey Bill thanks for your input. My GC were only about 6 to 8 inches long, at the time I put them in there. I don't have any bass that are 18 inches or bigger at least I haven't caught them. At the time I belive my biggest bass was about 14 iches. So my 6 inchers could have become lunch maybe?? Funny thing is though I haven't even seen them swimming around or on the top of the water or anything. But I know they are there becuase I had about 40 percent coverage of pond weed last year and I have only about 10 percent this year. They seem to be doing a great job on the pond weed. I think your right I need to help them out a little this year. My pond is only 1 acre so I can help them and it would take to much of my time. I agree with you that I need some of it for sure. If anything smaller fish hide out in it and I am assuming it does produce me some O2 during the day right? I fear I have so much though when it does start to die off I could have an 02 crash. I need to get my aerator in place ASAP!! I hope to have that going by Mid August. Thanks for your help.
