I purchased Pond Shock from Riverdale Supply after a very informative conversation with Lynn. I have had Koi for over 20years and the spring set-up can always be a daunting task.

I winter my Koi inside in tanks so moving them back out into the ponds is always a little concerning. Wanting to have the water in the best condition and getting the filtration system up and running with good bacteria for biological filtration is the top priority. I have tried many products over the years to kickstart the process including using mature media from my indoor tanks.

Nothing has compared to Pond Shock the results were amazing! Not only does it provide good bacteria, but the water clarity is perfect. I have never had the pond look so mature so fast. I always trying different ways to improve water clarity.....  this product is the easiest to use and the best results I have ever seen! NO NEW POND SYNDROME!

Thanks again Lynn for the recommendation.... I am telling all my Koi friends in the area about your product.

From a happy Koi Keeper....
