I have used these spring summer and autumn for c. 5 yrs. They benefit water quality and contribute to a healthy environment for fish and wildlife in my natural, pump free pond.

Bought this thinking that it would help to clear the waste that was in suspension in the water in my Koi pond. However, it did absolutely nothing. and shortly after using it, I lost one of my treasured Sturgeons 44" long. It seems strange that until I used it, the sturgeon appeared perfectly fit, although there is no proof that this was the cause of his demise. To remedy my problem, I had to to a number of 3/4 water changes in a short period of time, but as for the pond bomb - useless.

Simple to use by just popping it in your pond. Difficult to say how effective it is in terms of the health of my pond. It didn't clear the water at all but I didn't expect it to. Waiting for the UV to clear the water so I can see if this product has cleared the sludge as it says it will/

It takes a few days for the water to clear when I put the pond bomb in my pump water filter. I have two ponds and tried it in the smaller pond first with good results so got one for the larger pond as well.

Well I personally love this product. I turned off the UV about 5 months ago and found the water is clear and I don’t have to empty and clean filtration unit until each season ends. I clean sponges about once a week in this hot weather else once a month
