It’s 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.

Concentrated
This pond dye is nice. Doesn’t take much to make water blue. Hasn’t ever hurt the fish. Last a good while in summer. Last lot longer in winter months. I’ve bought it several times.

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.
