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

Non greasy, not much white cast compared to other mineral sunscreens
Size: 5 Fl Oz (Pack of 1)
The only one my 13 yr old will tolerate. Its the least greasy feeling of any mineral sunscreen we've tried. At 19% zinc oxide, I'm happy. Its also the least "white" cast of any we've tried. My Fitzpatrick III daughter is happy about that

Liked the old formula more :/ very drying
Size: 5 Fl Oz (Pack of 1), Size: 5 Fl Oz (Pack of 1)
We have used this for the longest time because me and my middle child have an allergy to chemical sunscreens. I remember last summer the formula was slightly more greasy but I preferred that. While I do like how protected my skin is (we haven’t burned at all even with the new formula, even after swimming for hours and not reapplying) it is extremely drying to where my skin looks like it’s cracking and feels very hard to wash off. Like I can still feel it on my skin after showering. May try a different one :/ super bummed! I feel like it is also hard to rub on skin because it absorbs so fast.

Great product, not the best packaging
Size: 5 Fl Oz (Pack of 1)
Glad I got this. Just returned from a two-week dive trip in the Caribbean. Lots of sun of course! I applied this product on my face and neck prior to first and 2nd dives - I never burned. I'm fair skinned but not a magnet for sun burns. I did not have a prior base that I can speak of. The product works well, and blends into your skin fairly quickly, avoiding the white out from other mineral products.
Downside - the container has some type of flow restriction. This had the effect of periodically not letting product out and then spurting out all of a sudden. Not sure if a dud, but except for that I would say absolutely I'd buy again.

Very happy with
Set name: Face - 1.7 oz.
I really like this. Quickly clear after applying. No sensitivity issues. Moisturizing. It does leave a sheen which I personally like and doesn’t feel overly greasy to me.

This sunscreen has worked well for me and I like that it is a mineral formula
Set name: Face - 1.7 oz.
This sunscreen has worked well for me and I like that it is a mineral formula. The main thing to know is that it can take a little effort to rub in fully so you do not see it on your skin, but I do not consider that a major problem. That is pretty normal with many mineral sunscreens, and I would rather deal with that than use something that does not agree with my skin. Once applied, I have been happy with it and have no real complaints. Overall, it has been a good face sunscreen for me.
