Sanco Industries Crystal Blue Pond Booster - Crystal Blue Pond Dye & Natural Pond Cleaner Combo - Treats up to 1 Acre - Crystal Blue Water while Reducing Muck & Sludge - 1 Gallon

Cattle dog dove in while I pouring this out and he was not phased, blue tint washed right off.This was the next morning after treatment with just 1 bottle. Our shallow end to the right is only about 4’ deep the other end to left of picture is about 20’ deep.The color I purchased before lasted me 6 months not sure how long this tint will last but I love the color

I tried this on my small pond and in a water feature and it really worked well in the water feature all spring long to keep the water clear. I didn't care for the effects it had on my pond and will probably continue to use aquashade there.

10 years ago my pond was a disaster. Algae, duckweed.... you name it. I cleaned it out twice with an excavator. it just turned to crap within a year. I invented a duckweed removal system that works perfectly. Once I cleared up the surface issues I went after the mass of weeds that always form. My 3/4 AC pond is nearly 15 ft deep. The concept of using a dye to reduce photosynthesis is not new however, which type/brand of dye used is critical. I tried several others before I used Crystal Blue. Full disclosure, I doubled the dose as I had with the other brands. Only Crystal Blue held up. OK... the water looked very blue, almost too blue, but that toned down after a while. At one point I was concerned that my white dog would turn blue if he went in the water. It didn't happen, obviously. The watercolor stabilized, the weeds never returned, and the fish started to repopulate. I'm proud of my pond. It is a major beautification object in my back yard. Constantly get compliments on its appearance. Getting ready to treat my pond this week in upstate NY. Crystal Blue...very happy with it.

My pond was in bad shape because it was shallow and froze completely this winter, killing the fish. Afterward, the pond had a terrible odor and looked dirty and disgusting. After a few rains, it filled up again, but it still smelled awful and looked cloudy. I tried Pond Booster, which claimed to remove odors, restore bacteria levels to where they should be, and eliminate decaying materials. I walked around the edge of the pond, pouring a cup here and there, until about half the jug was used. (That was probably too much!) After one day, it was obvious the entire pond had turned blue, and after a few more days, the pond was simply beautiful. The smell was completely gone, and the water looked fresh and beautiful, like ocean water. I was so impressed! I highly recommend this product. It says it is safe for animals, but I kept my dogs out of the pond for several days to be sure. I'm seeing frogs down there now, (and even some snakes) so it's apparently becoming full of living creatures again. I have one warning: be sure to wear gloves when you open the jug and pour it. The dye is very dark and will stain immediately. Also wear something that you wouldn't mind getting splashed. My fingers turned blue for a few days, but the dye eventually wore off. I will buy this once a year for use once in the spring and once before winter sets in.

This product did not work on our one acre pond...color lasted for a few hours only. It was beautiful an hour or two after pour and then dissipated by next day.Co. tried sending a replacement but this container did not work either. Not sure what the problem is with this product or if it’s not the correct product for our goals but Company was very friendly and easy to deal to deal with.

I use it to dye my small pond. My family does swim in this pond and it keeps the bottom from being slimy

Fast acting, smells ok. I should have worn gloves. I had smurf blue hands for 2 days. We'll see how it does for the muck on the bottom. Will update if I see any changes.

24 hours after application: I put in about 40 ounces in my pond. Its a little over half an acre in size. Applied it via a 1 gallon sprayer. Filled the sprayer with water almost half way and then added the pond booster. Pumped it up and then started spraying in various locations on one side of the pond. I cant get to the opposite side because of the brush. Anyway initially it turned half of the pond a dark blue color, along with the weeds. Panicked some of the fish and the turtles avoided the blue initially. Watched it slowly spread for a while then left. Next day it looked alot different. Was more green then before but expected that because of how cloudy the water in my pond has been. It has spread all through the pond though its still alot darker on the side where I sprayed it. Waiting to see how it looks next week. Will edit this and put in how its doing then. The fish and turtles seem to have settled in. Fed them and they fed normally. As in the turtles trying to hog the food. Greedy things. Got a few of the Florida Softshell in here. Big ones. A couple with shells reaching 16 inches.The water today is still cloudy. No settling out yet. But expect it to take a week before its noticeable. As I said. Will report back here in a week. Add some photos then as well.

This really works. Even though I have a good filtration system and change my uv bulbs regularly during the summer the pond water always turns green. Just a small dash of this stuff and the water turned to a deep blue, almost black colour. I’ve had it in for 5 days now and the water is still dark blue. I don’t see any algae on the water so assume it’s working. The science behind it is that it blocks the sunlight for reaching the bottom of the pond hence not allowing the algae to grow as it needs the sun. There’s no way any sunlight will be getting to the bottom with the colour it is so guess it’s working

Perfect colour blue for the water. Have used other pond dyes but this is by far the best value for money. I use it in a large water feature and the colour represents the beautiful blue water as if on holiday. The more you put in the darker it becomes, so best to let it circulate for a few hours before adding more to get the colour you require.

This enhances the pond water giving it a very nice crystal clear blue colour. easy to use just follow instructions on the product, and only add a small amount at a time and wait for it to circulate around the pond then add more to get your desired effect / colour depth. highly recommend.

Well it turns the water blue ok but I haven't got a clue what else it does but still I feel like I am back in the Med instead of being locked down in our garden.
