Secret to Crystal Clear Koi Pond Water

 I can't even start to tell you how hard it has been to keep my koi pond crystal clear. I used lots of chemicals and monthly water changes. I honestly didn't know if it was possible for me to achieve crystal clear water without redoing the pond and adding an underground filter. 

Last summer my grandson and I were at the pond and he said a nice waterfall would be cool. I had my pump sending water to a medium size filter box and running down a short stream. It looked really nice but didn't do much for the water clarity.

I checked on Walmart and found this large waterfall box on Walmart. The price was reasonable, so I added it to my cart. This is a big box so plan on adding lots of rock around it to get a nice waterfall look. Then, and I think this was the real key, I bought some bio balls and added them to the order. 

I already had an extra pump which pumped about 2000 gph, so I used it. I also had a 1" flexible hose.

The product came on a day I was busy, so we quickly hooked everything up and just set it where the stream was, replacing the smaller box. I started the water running and went back to what I was doing.

The next day I walked out to the pond and looked in and I'm pretty sure my jaw dropped, and my eyes popped out. I could see the bottom of the pond! The fish looked tremendous. I called my grandson and told him to come over so we could build the waterfall.

His reaction when he saw the water was like mine. We tore into building the waterfall and put the smaller box back for the stream. I had plenty of bio balls, so I added them to that box as well.

It seemed every day the pond looked clearer. At first I cleaned the filters about every two days but, once things really cleared up, I went to once a week and by the end of the summer, it was about once every three weeks.

We were both happy campers! For the winter I pulled the boxes and just left the pumps run so the water wouldn't completely freeze in our Ohio winter. 

Just opened the ponds yesterday and returned the boxes. You can see from the picture that I have work to do around the pump, since the weather is finally breaking. But you get the gist. I'll clean the filters more often to start and once the water gets back to crystal clear again in a week or two, spend far less time than I ever have working on the water.

If you have a decent size pond, I urge you to get the waterfall box and particularly the bio balls. You can thank me later.
