Not my pond but helping 1/2 pond bottom diffused aerator bad outbreak of the following: Treating with Cutrine Plus and Sulfate Crystals w/o much luck. Would mixing in some Cygnet (surfactant ) help? Was thinking of adding 10-15lbs Tilapia? Looks like suspended particles/algae in the water as well.

Yes a surfactant helps greatly with the liquid treatment. I am treating a water net algae right now and adding the surfactant made a good difference in my treatment. Dave
Thanks Dave 1 acre pond.

Half acre, or half pond? You'd need 20 pounds tilapia minimum, or more, if a half acre

Half acre pond, I believe he's going to try the Tilapia , any other advice on chemical treatment?

Treat in the morning on a sunny day and will probably treat half and then wait awhile to treat other half to avoid potential DO crash.

The Chara in the picture appears to be a very large biomass - deep and thick. It will take lots of effort in terms of chemical, manual removal labor, and/or fish to reduce it. Consider using all three methods. Be aware that if it is all chemically killed at once there could be a oxygen shortage to kill fish.

Hi, I'm new here. I live in michigan and have a 1/3 acre pond. I have largemouth bass, hybrid bluegills and channnel catfish. I also have an areator. I have been battling Chara for years without much success. I use powerderd copper sulphate, copper sulphate crystals and cutrine plus. The FA is taken care of but the Chara is heavy.I try to mechanically rake it our every year but I'm getting up in years and it's exhausting. My first two years I tried Karmex and it did a wonderful job but reading the label scared me and I have not used it since. The Cutrine plus label says you have to wait till the water temp reaches 60 F before application. But the darn Chara grows all winter (in Michigan!). So either way If I kill it or not I still have to rake it. Also the level of my pond fluctuates about 3 feet from spring to fall. So When I used the karmex I got a ugly mud bad around the pond in the fall. I'm wondering if Hydrothol would work better than the cutrine plus. Or if there is a better method. HELP !!

There is a much better method but your state does not allow it - grass carp and tilapia both eat it very well. The tilapia also eat the algae before the Chara. I think some in MI have used tilapia so there may be a MI law gray area on this. One has to be careful to not add too many because you want some Chara present to use nutrients and naturally compete against/with the filamentous algae(FA). It is a battle between Chara and FA for nutrients. Chara is less offensive than FA so in my experience it is best to have some Chara that reduces the amount of FA.

MI Native: Tilapia is not on the outlawed species list in MI. You may use in your pond but the issue is getting a big enough supply of adult TP to your pond. You can order fingerlings online but you need about 20-30 pounds of adult as a recommended stocking. THen, the problem is that the adults don't do that much eating, but if they have a few successful broods, the thousands and thousands of young mouths eating will make a dent in the weeds. The growing season in MI ponds is short and the fish don't lay eggs till water hit a certain temp. Then of course the adults and the young all die off in Nov when water temps hit 50-55 depending on what strain of TP you have. So the next season you have to start over again.
I only know of one fish hauler with necessary permits to haul TP into SW MI so you could connect with that outfit and when they bring TP to other SW MI ponds you might be able to get in on some. Perhaps there are other haulers in the SE part of the state but doubt if you are in mid or northern part of MI or the UP that you have options outside of shipping in 1-2" TP.
