DefoamerKusuri 1 litre

Works well. In fact worked immediately (the box says within one hour). I have a 1000 liter pond with a small waterfall and so foam occurs - especially after heavy rain fall.I bought this and even though there was really no foam issue when I received it, I tried it (you know, toys has to be tested upon receipt). It had immediate effect on the little foam there was. Very impressed. Even around the waterfall it showed no signs of foaming at all and I used less than described.Still an early user and I will update after some test of time but for now I give it my thumbs up.One note though: The clear liquid inside the sealed bottle had what appeared to be algae growths. Not much but the type you would expect in a soda can who has been out in the sun for days.... strange, as the bottle was sealed and far to the "best before" date. I used it anyway, and it worked... so perhaps this growth whateveritwad is normal.

Great product dose what it says on the tin
