Crystal Blue Natural Pond Cleaner - Muck and Sludge Remover, Safe for Koi - 1 Gallon

I haveca small backyard pond that was really murky and dark. I've tried a bunch of other products- more expensive ones and this one worked the best. It cleared it up w/i a day and has stayed clear for a week now w/o being retreated. I only used 1 cup and bought the gallon so it will last for a long time. Koi had no reaction to it and pond is crystal clear! Good stuff!

We just started using this. We changed to this product because it's cheaper than what we had been using.

I used this as directed and gave it plenty of time to start working. My water is somehow worse than when I started. This is snake oil. Save yourself $39.99 and throw a penny in your pond and wish for clear water. You’ll probably get better results.

We had a lot of moss, didn’t actually think this would work because we’ve tried several other things first, but it worked! Got quite a few uses out of it, killed the moss without destroying the pond life within

The service was fast. The product did the job. Paddled around the perimeter of our pond and added two gallons of this product. In a weeks time most on the algae and other growth has been reduced to almost gone.

I think it is helping to clear the water but I don't see the muck getting better. I will stay with it to give it a fair chance. I say it is helping with clarity because I have a lot more weeds. I assume that's from increased sunlight

Perfect

Great product. Helps reduce muck. And the appearance of the surface is much cleaner.
