aquatic herbicide sonar Sonar AS Aquatic Herbicide bottle (32 oz)Sonar AS Aquatic Herbicide is a professional grade systemic aquatic herbicide trusted for long term selective control of invasive aquatic weeds in lakes, ponds, reservoirs, irrigation canals, and other freshwater systems.

Sonar AS Aquatic Herbicide is a professional-grade systemic aquatic herbicide trusted for long-term selective control of invasive aquatic weeds in lakes, ponds, reservoirs, irrigation canals, and other freshwater systems. Powered by fluridone, Sonar AS provides season-long or year-long control of many troublesome aquatic weeds with a single application, making it one of the most effective and economical aquatic vegetation management solutions available. Widely recognized as the industry standard for duckweed control, Sonar AS slowly disrupts carotenoid production in susceptible aquatic plants, leading to gradual bleaching and plant death while minimizing oxygen depletion and water quality disruption often associated with rapid vegetation collapse. Sonar is highly effective on duckweed, hydrilla, coontail, Eurasian watermilfoil, bladderwort, and other labeled submerged and floating aquatic weeds. Unlike many aquatic herbicides, Sonar AS has minimal restrictions on recreational water use following application. Swimming, fishing, and livestock watering may continue according to label directions, though irrigation restrictions may apply for certain sites and crops. Developed by SePRO, a recognized leader in aquatic plant management, Sonar AS has been trusted by professional aquatic applicators and lake managers throughout the United States for decades.Features & Benefits

Perfect for Adding Privacy to a Piano Studio
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
I Ordered the 2 Panel version which is way too big for my needs... that's on me. So keep in mind that the picture shows a fabric made for two panels only being used on one and hence it is not pulled tight; it would pull tight and not be so wrinkly if it was set up properly as two panels. The metal pools that make up the panels seem to be well made, stable, and of good quality. They were very easy to put together and they stand up tall with plenty of height. The appearance of it with the fabric on it isn't as elegant as it could be, but it still looks good enough. The material is plenty solid, not allowing light through it, and thereby making a solid barrier. I am using it to block the view out the studio door when a student is sitting at the piano to avoid distractions from the hallway. It will allow a student to enter the studio with our distracting the student who is at the piano.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room.
The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams.
The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money.
What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.

Nice quality, looks brand new even with daily use! Worth it!
Size: 6 Panel, Color: White
I got the Rose Home 6 panel room divider folding privacy screen and I LOVE it. I use it every day - extending it out to both block the sun, provide a backdrop for my plant wall, use as a backdrop for zoom calls, create privacy at night in front of the big windows and clear doors, and make impromptu study privacy walls in the office. This 6-panel has been the GOAT! Even though the screen is made of a woven paper material, it is still going strong despite daily use and has NOT broken anywhere. The frame is taller than other folding screens I've purchased and this one is also heavier and sturdy. Additionally the hinges fold open in BOTH directions (some screens only fold open in 1 direction like a Z). I use the folding screens indoors, but they have no issue with the AC or fans for wind resistance indoors. Sometimes I use them to hide storage or junk in the corner and make the room look neater. I also have a different brand that is the same material but has 8 panels and I love them both. I got 2 others that were made from synthetic canvas webbing belt/leash fabric and those break so fast - I just had to throw 1 away. This one is worth the money, even after daily use, it looks brand new!

Already assembled!
Size: 8 Panel, Color: Natural
Came way sooner than the estimated delivery date and it looks awesome! Biggest plus is it came ALREADY ASSEMBLED! I was expecting self assembly but maybe that's on me for not reading the specifics. Hoping it's the right size for my new studio apartment. So far the look and functionality is 10/10
