Say Goodbye to Algae with Cutrine Plus

Cutrine Plus is a 9% chelated copper algaecide ideal for controlling algae in lakes, reservoirs, farm ponds, fish hatcheries, irrigation systems, and more. It’s far less corrosive and more chemically stable than similar products, and effective even in hard water.

Cutrine Plus works on contact, breaking down algae cells and disrupting photosynthesis. It controls planktonic algae in 24–48 hours and filamentous algae in 3–4 days. Apply early in the season when water reaches 60°F or above for best results and reduced dead growth. Suitable for treating surface algae and algae up to 3 feet deep.

Application rate: 0.6–1.2 gallons per acre-foot of water.

No water use restrictions. Do not use in water containing Koi or hybrid goldfish.

Not available in: CA, CT, ME, MI, NJ, NY, OR, WA.

Cannot be shipped to Canada.


Cutrine Plus: Keep Pond Water Clean and Clear!

Control typically lasts several weeks to several months, depending on local conditions. Multiple applications may be necessary to maintain season-long control. Reapply as regrowth begins to appear, allowing 1 to 2 weeks between consecutive treatments.

Heavy or out-of-control growth may require more than one application or physical removal to regain control. For best results, apply during periods of minimal water flow. Apply early in the morning on a calm, sunny day. Ensure a minimum contact time of 3 hours.

CUTRINE-PLUS Liquid may be toxic to trout if the carbonate hardness of the treated water is below 50 ppm. Most surface waters exceed this threshold and pose no risk. If you're unsure, test the water using Water Hardness Test Strips. Do not use in water containing Koi or hybrid Goldfish.

To apply: First, determine the volume of water to be treated in acre-feet. Use 1 gallon of CUTRINE-PLUS Liquid per 1.5 acre-feet of water. Dilute with at least 9 parts water and spray uniformly over the water surface using a sprayer. For improved surface penetration, allow the material to fall in coarse droplets.

Tip: Break apart dense surface mats before application to improve algae contact. Treat heavy infestations in sections to help prevent oxygen depletion.

Sturdy & well made & they stay in place!
Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters, Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters
Wow, these are really nice & well made sunglasses!! I love them better than my prescription sunglasses that I paid a ton for that I really don't need when I am out in the sun. They have some weight to them and don't feel like cheap sunglasses you get off the rack in a drugstore and they fit comfortably on my face and nose. The build-in nose pads hold them in place so they don't slip down my nose!! They come packaged with care in a nice carrying case and there's a lens-cloth included in the package. The price on these won't break the bank and I'm really glad to have found them as I do spend a lot of time in the sun or bright light.

Soft case, not universal, not worth the price
Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters, Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters
I didn't pay for these, but priced at more than $70, I wanted to try them. The description is confusing if not misleading, stating "Quay merges music and fashion to create trend-forward designer eyewear for any moment or mood." Given the exorbitant price for a brand I never heard of (e.g., Raybans may be overpriced, but they come with a 24 month warranty and it's a brand that's been around a long time), I thought that these shades played music. How else are ordinary $10 sunglasses priced at nearly $100? How do they "merge music"??? Answer: they don't. They're sunglasses. They're also not "Designed for a universal fit," because they're way too big for me, and I have a normal-sized head, and I have bought many pairs of sunglasses and nearly all of them fit just fine. In fact, this is only the second time I ever tried on a pair and they were too large, but the other time, those sunglasses, which were a lot more stylish than these, cost around $20. The case is soft, which is ok, I guess. Some people prefer it but to me, if a case will not provide any protection from being crushed, e.g., sat upon, or had something heavy put on top, then it's not a very good case. They also included a nice lens cloth.

Impressive lenses quality for polarizing that works
Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters, Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters
As much quality of polarized glasses that you can get for the value here with actively polarizing glasses that not only block bright sunlight but dramatically reduces glare and bright rays on light surfaces even compared to some "better" sunglasses that aren't polarized. You really have to test them yourself to see, and if you like the lenses, you'll like this! The lenses are dark grey, so they keep the true color of grass, trees, sky, everything, just with dimming effects which I prefer, it's not a massive change changing colors, it's more natural to me. The quality & style is high with the whole glasses feeling sturdy and smooth as you open them and put them on. It's made with some basic plastic frames, they have a nice softer texture that's almost silicone feeling, so they feel great & soft but also it helps support sitting on the nose and ears. Perfect fit (I'm a man, average head I would say lol) I haven't noticed any sliding around at all with these! Lenses are made from PC with polarizing. They feel thick, sturdy, and stay clean. I have only noticed one fingerprint so far after wearing them for 2 weeks. It definitely is a weekender look and case build. The edges sit a little further away from the skin so depending on the angle there can be a little glare and reflections of your eyes cheeks in the lenses. If I had to choose a part I don't like the most that would be it. Pretty glarey on the inside. On the outside, it's reflective to any light so lots of sunlight will reflect off and hide your eyes which I like. Aesthetics, usability, quality for the value, all make this stand out to me and I would definitely be packing this when I'll be in a lot of light, even for driving with the anti-reflection polarized lenses. Very impressed with this pair. I would like the sides to be closer but I guess I would have to get a different style, these are weekender, so all in all I'm a big fan!

Neat design with high quality lenses
Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters, Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters
These Quay sunglasses combine a unique bridge design with a sleek, modern style that stands out. At first, I wasn’t sure if I’d like the way they sat on my nose, but after wearing them, I found the look and fit to be both flattering and comfortable. The frames are lightweight yet sturdy enough for daily use, and the fit is secure without slipping during regular activity. The polarized lenses are excellent optical quality, reducing glare effectively while staying distortion-free, which makes them great for driving and outdoor wear. I’ve worn them for several hours at a time with no discomfort. For the price, these sunglasses strike a nice balance between fashion and function, offering a high-quality lens and a stylish frame at a reasonable value.

Bold Look with Good Sun Protection, Slightly Big Fit
Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters
I picked up the QUAY Weekender sunglasses in matte black mainly for everyday wear, and they definitely make a statement. The oversized rounded shape stands out and gives a modern, slightly edgy look. The lenses provide solid UV protection, and I’ve found them comfortable to wear for long stretches without eye strain. They are on the larger side, though. If you have a smaller face, they might feel a bit oversized or slide down slightly. The frames feel lightweight but still sturdy enough for regular use. Overall, they’re a stylish pair of shades that balance fashion and function well, especially if you like a bold, oversized design.
