You are in a tough spot.

I 100% agree with EWEST that it is too hot to stock grass carp now. Worst of all, I'm not sure the grass carp would be of much assistance this season due to the amount that is now established. If you can wait until it cools down a little, the grass carp will provide a little bit of assistance in the fall, but they will really start to make a difference next spring and summer. It may take two seasons for them to get it completely under control, but they will do it.

If you can't figure out how to post a picture, put it on some photo website, post a link to the photo, and one of the moderators will re-post it for everyone to see.

The photo would be helpful to know what is floating on top of the water -- is it blue-green algae, is it filamentous algae floating up from the bottom, etc.?

Be aware that with coontail, you must remove everything you grab. Every little piece that breaks off and doesn't come out of the pond will usually turn into a new piece of coontail.

I'm not a big fan of chemicals, but sometimes they can help as a last resort. We have a few real experts here on the site, especially Kelly Duffy. They may be able to provide some assistance on eliminating some of the coontail. The main thing is that you don't kill very much at a time. When it dies it will sink to the bottom and remove even more oxygen from the pond.

I normally don't have any issues here due to lots of wind, and it doesn't get as hot as where you live. But, we've had several calm days in the 90s. I woke up to one of my ponds covered in algae this morning, with one floating dead hybrid striped bass about 20 inches long. I moved my two-inch semi-trash pump to that pond and ran it for about 30 minutes this morning, about an hour mid-day, and I'll run it again for about an hour this evening around sunset. I choke the 2-inch output hose down to 1-1/2 inches, and it puts out about a 50-foot plume of water that I shoot high into the air and that falls into the pond. It isn't the best aeration, but it does help in these situations. 95% of the algae that was there this morning has sunk. I'm not sure that is good, but ...

Hopefully, a few others will pipe in with better assistance than I can provide.

Regards,
Ken
