Does this work on watermeal?? Also do I wait until the weeds are present or can I start treating the pond before the weeds appear?

It will kill watermeal. Treat it just like duckweed. You'll need dynamic surfactant also. This stuff is expensive so I wouldn't waste it on pre treat.

It doesn't start immediately; however, a day or two...maybe more. I can only say truthfully that this stuff KILLS weeds and everything else. Don't even think about spraying close to plants you want to keep. Use a paint brush to paint it on weeds and grass close to those plants.

I've never used karmex. I talked to a man I know at a feed store about duckweed on my pond that looked like you could walk on. He told me about Alligare. I have a 1/2 acre pond. I walked around the edges with the 5 lb bag and a scoop. It worked very slowly. Five weeks later, no weeds. Very Happy.

you're not supposed to use it in a pond but everybody does and it works very well. I mix it up a partial bag in a five gallon bucket and string the mixed up herbicide along the bank a couple feet out. the chemical works any season for me.

go to "Pramitol 5ps, 2 Lbs" on Amazon. It gives directions/ sq ft and also has some reviews you'd be interested in. I had to double the application for a rock covered area that didn't really have a lot of weeds at all. It was early season so weeds hadn't come yet. I cannot stress enough that a complete water right after is essential.

I haven't tried it on horsetail weeds. My best success with those is pulling them out before they turn pink although it is hard to identify them .

Love my Dragon! This will kill anything. Some weeds, mostly perennials, you may need to flame twice to totally kill an energy left in the roots. What I like about flaming weeds is that the result is immediate. I usually wait until a light rain then go to town around the house with no risk of mulch catching fire. Good luck.

This is a product I use to prevent weeds from sprouting from seed. So I would recommend you use live plants or slit the paper where you want to plant the seeds. Remember this will biodegrade each year. I love it because I do not have to use herbicides and I can still plant. However, the down side is until I get weeds under control in an area, I have to reapply it each year. I have an acre of untamed land and am slowly getting it under control.

We used this to successfully get rid on the watermeal in our pond, which is very very hard to kill. This killed all the vegetation in our pond. I would not use this if you are concerned about your water lilies.

It takes about a week, maybe a little more, to see it begin to work. Within 2 weeks the nutsedge is obviously dead or close to dead. This stuff works great on this weed that I can't otherwise kill. There isn't much I can us on my floratam (version of St Augustine) grass. Sedgehammer (which goes by a couple other names as well) finishes what the atrazine doesn't touch. Be prepared to spray a few times though because the first pass will miss some. It only kills the sedgeweed that is actively growing.

When I install by unit, my pond was neglected for about two years. It was in VERY poor shape. I back washed the filter every couple of days to start and gradually backed off to once a week. It took about a month before I started seeing results, but my pond is crystal clear. I also use a pond clarifyer every couple of weeks. I hope this helps.

rack out the old dead grass. Best time to add seed after it is mowed and yes it will crowd out the weeds

We have Floratam grass and it works well, but less is better. If you use too much it stunts the grass for a couple of weeks but it is the ONLY product that works on weeds. We LOVE the stuff, just use as directed :-)

Well directions say it has to happen during germination ... Which I assume to be spring. I'd test it on a small area and see the results. It did not seem to kill crabgrass on the spot. Kind of seemed to help the other parts of my lawn from the crabgrass invasion so to speak.

Yes it works great and does not hurt the fish. I have used it yearly for 11 years to kill the weeds. We swim and fish and have dogs in it , no problem. Mine is large 3/4 acre and 25 feet deep. Just do half of the pond at a time if you have fish as it sucks the oxygen out of the water, and make sure you don't get it on anything else, as it will kill it.

Generally each Spring I have to clean my pond and I alternate between a full cleaning and a partial cleaning. What you describe is what I would consider a full cleaning and you should be fine doing what you describe. Keep in mind that the fish will still need oxygen when you move them to the large drums, so try to put an aerator or small fountain pump in with them to keep the water moving and full of oxygen. The partial cleaning I often do instead of the full cleaning involves a fair amount of work with a wet/dry shop vac and a pond net. The idea here is to try and leave as much water as possible, while still getting the gunk and muck out. I use the net to scoop out what I can first and then I take the wet/dry shop vac and try to suck up as much sludge as possible from the bottom of the pond. The advantage with this method is you don't have to move fish and you can do this in small steps. I often will do the cleaning over the course of several days. If you spread the cleaning out over several days then you can add fresh water back to the pond to replace what you suck out with the vacuum. This is less stressful on the fish since there is a smaller change in the water and pond chemistry as opposed to a full cleaning where you replace all the water. But sometimes the pond is just too dirt to do anything other than a full drain and clean. Good luck and yes adding the Microbe Lift after cleaning will be a good way to get the good bacteria and the pond ecology back to a healthy level quickly.

I could tell you that you should be identifying the exact weeds you want to control and keeping track of your local weather and soil temperatures etc. but....The stuff is pretty effective for a good 4 months and controls some weeds out to 6 months. I would just make sure I put it out at least 2 weeks before typical germination of the weeds you are trying to control, and even if you end up putting it out 2 months early, it is still going to be pretty effective. You could do 50% (max annual rate) for Summer weeds and again for winter weeds later in the year.
