Did not work
Second time trying this and it didn't work at all. Couldn't return for a refund because it had been all used and the bottle was thrown away. Algeais worse now than before using it.

Works great!
I bought this to give my water garden a black mirror effect so my plants stand out and to help hide the its they are in. I use a 6 ft round stock tank for my water garden since the ground is too rocky to dig. This product provides a rich deep black and lasts a long time. It also cuts down on algae build up. Well worth the cost

Worked as promised! Recommend! Needed to keep sunlight from plants taking over my pond

Shake before use
This dye is very concentrated and probably settles out after a while, so shake the bottle well prior to use. Its dispersal depends upon the amount of water agitation while applying the dye, otherwise it will sink to the bottom because it's so concentrated. For small ponds, a little goes a long way.

Not a 4x Concentrated product
Not happy with this product. I bought the black and the dark navy blue. My pond is approximately 1/4 acre and still had some tint from the previous dye in it. Over a 2 day period, I have added about a half gallon of each color and it is still not tinted as it should be. I beg to differ on the “4x concentrated” claim.

Black Pond die is weak.
Does not work well, want cover the pond like the 4 times blue will, so it will take 2 bottles of this black to do a good job, it’s just not strong enough. Will not buy this black again a waste of money.

Black pond dye
I really like the Black dye good mirror effect color, and it seems to block out some light to stop plant and algae growth effectively. My pond has a high inflow of water but the color seems to last a few months.

To expensive for what it is
It is not collaring the water in pond as advertised We used 2 containers where one should be sufficient and after 2 months we had to repeat the process To expensive!!
