Not 4x but definitely 2.5!
Usually do 5 gallons of dye in my pond this is probably closer to 2.5 gallons equivalent, not 4. Still more concentrated than the regular 1 gallons I usually get. Would purchase again.

It makes my brown pond blue (ish)
My pond is a very cloudy, chocolate milky color on a normal basis. I use one bottle of this in my .9 acre pond and a few hours later the whole thing is is a blue-ish green color. If the water was clearer I'm sure it would be more blue, but it's starting with a very, very cloudy pond. They say it helps with algae growth, too. It's difficult to measure that impact, but my pond does have a minimal amount of it. I re-use every 2-3 months to keep the color. It does fade over this time, but it's still visibly bluer than it would otherwise be.

4X Blue Pond Dye - Transforms Murky Water to Natural Blue - Super Concentrated
This is my second purchase of this particular brand of pond dye. It is concentrated and therefore treats as well as a full gallon of most other brands! The price seems to have risen on most ALL of these pond dyes, so I found this one to be a bit of a bargain! Works great, easy to apply (just wear protective gloves when applying)! Also, disperses evenly in a very short while (TIP: Always try to apply upwind!). Great results and pleasant color. Color can be adjusted somewhat by the amount of dye used, therefore, start off with a smaller dose and add more for a deeper color!

Itโs impressive
My pound is a little one so this quantitie was a bit to much , i supposed to put only half of it. Anyways the pound color was dark bleu, I like it but i will search for a lighter Bleu color as this one it too bleu for my taste . Everyone single neighbor was amazed by the color of it and impressed in the same time.
