The Pond Guy RapidClear Flocculant, Water Garden Clarifier Treatment, Clear Cloudy Outdoor Koi Fish Ponds & Fountains, Plant & Animal Safe, 32 Ounces

Amazing. My koi dug up dirt from a potted plant I put in my pond and my water was brown. I tried everything, water changes, etc. This stuff made my water clear in days. It's literally crystal clear. My fish seem unharmed. I used LESS than the recommended dosage for the safety of my koi. It worked with once time use. I paired this with the beneficial bacteria packets.

Honestly, I was concerned at first because it seemed like a long time, but was a little more than a week, before I saw results. I was adding Clarity every day for about a week and a half. so I went through the first container of Clarity rather quickly. However, once my pond started to clear, I switched to only adding Clarity once a week. We are now almost 3 weeks in and the pond looks better every day. The fish don’t seem to mind and it’s great that I can actually see them!

Saturday morning I couldn't see my fish 3" below the surface. I got this delivered mid day and treated, then again 24 hours later on Sunday per instructions per "problem ponds". It's not even 6am Monday morning and I can see them swimming nearly 3 feet down. This after fighting the haze for over 3 weeks with two 30% water changes and another product. I was cautiously optimistic and worried about the price, but it was worth it - I'm sold and won't buy anything else going forward. Thank you Pond Guy! We have been flocculated!

Did a complete water change. Nice clean liner, and all clear water. Added amount per instructions at application rate. Immediately clouded as it says it might for few hours. "It may take several hours for water to clear depending on theapplication rate."As pics show, after several days!...still very cloudy, and clay lays on bottom and now must be vacuum whole pond liner. This wil take many hours. OR another complete water change.I did call to confirm dosage, and they very nice, just give more time. Unfortunately just not working, not clearing.

Really helps loosen the muck from the bottom making it easier to keep the pond clean.

I love pond guy products but they are expensive.

Works pretty good. I don't think mother nature approves. She'd probably want my pond green and full of fungas. Gold fish and kios don't seem to mind.

It's great!
