Airmax Pond Dye Plus, Nature's Blue Colorant & Natural Beneficial Bacteria, Large Pond & Lake Water Clarifier & Color Treatment, Shade Plants & Algae from Sunlight, Fish & Livestock Safe, 1 Gallon

Use gloves when using this item and DO NOT THROW OVER HEAD as the power will stain 🫟 your skin and clothing . And will last on your skin a couple of days. Lol It is favorite product to use in your lake or pond to keep it looking blue and help settle down the algae.

I have a 1500 gallon gold fish pond and a 7000 Koi pond that were looking a little sad and brown here in winter. And since the water clarity was good I was concerned about the views that might be open to heron, raccoons, possums. Yes I live in the city but have a nice woody acre. So I decided to try the Airmax Black Dye because the blue dye doesn't look good on waterfalls. Well the black is very pretty black with very little product used, but the water coming over the waterfalls looked neutral. That was good. The water in the test tubes for ammonia, nitrites, pH etc was clear so that tests were accurate. That is good. I hope that the lack of penetrating sunlight may slow down string algae as it warms up. But the darkness does not seem to affect water temp. Thats good. And the ponds looked really cool, deep black with the reflection the ads talked about. Until I decided to put some Natures Blue in one to try to get the Twightlight Blue that Airmax also makes but that I didn't buy. Unfortunately it did what ll blue dies did: make it a very pretty but unnatural blue across the waterfall and at the agitation at the bottom of the falls. When I received the products there was a slip enclosed that asked that if I could't give them 5 stars please call or email. I had 2 issues that were going to take my rating to 4 stars so I did as asked and emailed them my feedback. Much to my surprise I didn't get a defensive answer or an excuse as to why they must do what they must do. I got a real back and forth conversation that specifically addressed the feedback I was going to give about dosing for smaller ponds. As a result of the time and interest they took with someone who only spent about 50.00 with them, they have created a repeat customer. So my feedback is that the product is good but use increments of a half or one ounce at a time. If you have a waterfall the Natures Blue will make it look very blue...very bright blue, and I think unnatural. I am going to stick with Black or try Twilight Blue. Thanks Steve! You were a Blessing.

We have a smallish pond and like to keep it pretty. Although it is pricey the dye works well and keeps the water blue for a half year. Does not hurt or bother my fish.

Properly packaged and shipped on time. A little pricey in my opinion and no matter what I do, I get blue dye everywhere. However it seems to last and helps slow down plant growth which means less work maintaining the pond. I waffled on a fifth star but the price is what brought it down. I might try another brand one day but if it ain’t broke…. My pond is 0.1 acres and this bottle will last me one and a half seasons.

Used 1 bottle of black, great color, very natural. Pond is about 1 acre with average depth about 6-8 feet, 16 feet in center. Took a couple of days to assimilate but has a full consistent color shore to dam. The reflection of my green grass dam is amazing. (Ignore the weeds, it March and mowing season has just begun).

I depend on this product to keep my 1/2acre pond looking beautiful.

Darkens the pond water and helps with algae growth. Great product!

Makes pond color so beautiful! Used in a 1.5 acre pond and made it color up well! Does not kill fish, keeps water clean and also keeps it tinted to help the underneath weeds from getting sunlight!

This product did help to keep the algae down but made it harder to see the fish until the came to the surface

LOVE this product. i poured 1/3 of bottle into our pond and within 20 min our pond was a gorgeous blue color and with in a couple days it was crystal clear. I have enough to do some treatments in the spring again. I will definitely buy more

Packaging not suited to the product. All four packets were spilling into the plastic bag holding them. One should not only wear disposable gloves, as noted on the packaging, but preferably gloves to the elbows and a long plastic apron to handle the packets. Due to the inner packets being broken, the loose product got on my arms and clothes. The product permanently stains whatever it touches and the stain is not soap and water soluble. You have to wait for you skin surface to wear off naturally before you'll get rid of the stains. The packaging says to use diluted bleach on clothing ... that still removed the colour of my jeans. I'm too old to find the bleached jeans look attractive. 😄

Love this product for out pond. Use caution because a little goes a long way .

I have used this product for a couple of years and it really works well to get rid of the algae. We have a large, deep pond and it protects the fish from the herons as well. The water has a nice deep blue color. It was delivered on time with no problems.
