CrystalClear PondShock

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

This is no good! I had an established 700 gallon pond that had been doing fine with the exception of a bit of algae. This bomb killed all my fish. Within a couple days. 20 4 inch goldfish, 1 6 inch koi, and 20 minnows. Plus a couple bull frogs

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.

My pond was SO murky with silt suspended in the waters. My skimmer begged to be cleaned every other day. I dreaded cleaning the pond, but feared for the health of the fish, so I pulled out the pond vacuum and practically killed it trying to suck up all the sludge on the bottom. I finally got the vacuum to work as a pump, draining 3/4 of the water out of the pond, then using the net to shovel out loads of muck. I cleaned both the skimmer and waterfall filters, which were FULL of muck. Refilled the pond with well water and added 2 Pond Shocks to the 5000 gallon pond. The two photos show the difference between when I added the treatment and two days later. Folks, Pond Shock is good stuff, but it's not a complete miracle worker. You have to invest in regular maintenance or do a mini overhaul like I did if you don't do regular maintenance. Now I have clear water with sludge patches on the bottom. I'll have another go with the vacuum at those spots......

Did not work in my pond

They work great at keeping our ranch pond balanced. However delivery method is awful. These are fragile and not shipped in a box, instead the paper bag/envelope. The pond pods box is often crushed and often leaking.,,

What I have learned. CrystalClear PondShock ball works as it should if your pond is a balanced ecosystem, if you're having algae problems it's not from this ball, it's because your pond is getting too much sun and/or you don't have enough plants to take care of your pond waste material, that's simple more plants less algae, less Sun less algae if you have a small pond and you can place some kind of shade over it you will have less algae but the more plants you have will compete with the algae and algae won't be able to form because your plants will be eating the waste product that feed it. So I highly recommend this ball it works perfect in the pond and it does not harm your fish or your plants. I have this ball for my pond on Subscribe and Save. So when I need it I have it.

Works pretty well.

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.
