CrystalClear PondShock

Works great. Hard time clearing the water. This works great, little longer to work than I thought, but be patient.

This product does not work whatsoever.Literally.Nothing happened.I would not recommend it

Used this product when I opened my pond for the spring. It was amazing how fast it cleared up the pond overnight. I bought another one and plan to use it every other month for maintenance. Awesome product.

Be aware that Amazon frequently mishandles this product the product itself is good but half of the times I receive it Amazon packs it in a box with other heavy things which crush it and cause liquid to spill all over all of my other order items or they put it in an unpadded bag and throw it on the ground breaking the container open and causing it to leak inside the bag I don't know what the person selling this can do about Amazon handling the liquid contents of their product otherwise the product seems to work fairly well to keep the Pond clear.

I have a 1500gal koi pond. Every spring I have it drained cleaned and inspected for leaks and have any other maintenance performed. So, yes I start with clean water. After treating the water to put my fish back he tosses in a bomb. Every week I add beneficial bacteria and just a small amount of algicide. Monthly I add a new bomb. My water remains clear and the muck build up is minimal. My pond lilies are growing like crazy! But you need to remove the dying leaves, they create the muck. Yes, I have the algae blooms when the heat spikes and the rain drops the temp of the water. I try to add a bit of fresh water in the heat the reduce the water temp and control the algae. You need to be patient with the algae bloom, too much algicide, and not enough aeration will kill your fish. I have purchased solar powered aeration to help. Owning a pond is a science, an art and a love. A beautiful, clear koi pond is not cheap to maintain. It takes time, love and educating yourself and then you will have something that you can truly enjoy. One product will not maintain your entire ecosystem. However I give this product 5 stars for what it is supposed to contribute to my ecosystem.

Great product. It has really helped the pond look clearer. Easy to use ... just open and drop into the pond.

My Koi pond is in direct sunlight most of the day and every year the pond turns bright green. The owner of the local koi supply shop said that the fish don't care if it is green. But I care... because I cannot see the fish. It just looks like green soup. So this year, before the green took over but it was clearly starting to take hold, I put in the pondshock ball. The green went away but the water turned kind of a brown color that didn't go away. I also have a UV filter inline with the supply to the waterfall that usually cannot stop the green from taking over. I turned the UV filter off so that it would not kill the live bacteria. After a month the green started coming back. So I turned on the UV filter and the water cleared. I am hoping that the pondshock ball dealt with the algae that is on the sides of the pond and in the waterfall rocks so that the UV filter can possibly kill any algae that is introduced in the water before it can take hold in the rocks. We will see.

Waste of money did absolutely nothing.

Super.produit

Ni funciona con agua verde. Me imagino que funciona con agua clara

Well it doesn't even remotely do what it says. I have a small pond and it did squat.

Has helped keep pond clear. I have bought more.

used this once and the pond was fine and then it was really bad? which made me think it's one of those products that works that way so you keep buying them and using them. by the end of the season the pond was fine again (there are fish). honestly it's left better as is, this product is trash and I do not recommend.
