Crystal BluePlex Mate Aquatic Surfactant for Herbicides - 8 Ounces - Non-Ionic, Increase Product Coverage, Increase Product Penetration, Increase Product Effectiveness

Love this, works great killing weeds in pond, at least the weeds we had. A+

The fastest and most efficient herbicide I’ve ever used. Didn’t harm fish, frogs, etc. I will buy again.

I bought this as a residue-free eco-friendly surfactant to clean green slime algae (cyanobacteria/bluegreen algae) off of aquarium equipment. It is very effective, but a little dab will do ya, and it takes more rinsing than I expected. I put my lid back on and was horrified to have a surface foam for 2 days. Luckily, the dose was so low that everyone was ok, and being eco-friendly, the bacteria broke it down quickly.

good concentration for dark dye

My dad uses this with good results on his clogged canal where he lives. Keeps the weeds controlled for him.

I guess I needed to read the fine print because this is a very small bottle

I use this product with a liquid weed killer spray. It does a good job of allowing the chemical to stay on the leaves especially ones with a water repellent surface. Of course he wouldn’t need it on all weeds. I have I did find that for very water repellent leaves like clover I needed to use double or 2 teaspoons per gallon. It works very well when used at that rate. You could achieve the same result with a liquid detergent but it foams too much when you mix it up and foam doesn’t work well in a sprayer.

Second bottle I have bought,Works great, to blue mark what I spray, as I go, efficacy of use of expensive herbicides, also insures accuracy of placement as I go especially when hot out and in the sun spraying, but cap leaks,Manufacturer needs a much better cap that is leak tightSo I have transferred to a better sealing bottle, a small plastic bottle that is leak proof, but have put on, labelled it what is so no confusion risk for anyone including myself
