Koi pond green water cure without chemicals

You are a GENIUS!! We battled algae bloom all summer here in Michigan (USA) in 2015. We finally got clear water when we had a 3-day cold snap in mid-August. I am sharing this with all of my friends, plus the Pond Place in Milford, Michigan. I almost bought a $2500 UV light filter for our 8,500 gallon pond. Our pond was a pea soup green for most of the summer.

Awesome, my pond goes green as soon as the weather starts to warm up. I'll be trying this next summer. Thank you!

Simple but effective. I used the same kinda setup during the summer, I've even managed to build a small DIY sieve filter . Beautiful koi btw

my man that has just set me up on my pond to do he same thanks a bunch much appreciated great idea to help ya filter sysem for next to nohing cheers again

Hey Guy,  That's a really cool idea. I'm going to try it as soon as I get what I need. The filter I've rigged up work really great to, but anything to keep the water clear is a plus in my book.

Amazing koi pond. You should really consider adding pond plants to help eliminate algae from starting.

Thanks for the vid. you are a genius.

I don't own a drill but I am going to purchase one. I had string algae and what I was using is something that I rigged up. It was an extension pole with a women's round Bristle hair brush attached to it.

The guy had UV already- obviously wasn't enough so this looks like a good solution to me. Fabulous garden btw!

I must admit I watched this video and thought another YouTube load of rubbish, but I thought I'll try it and give it a go.I attached the stocking about 17:00 and the next morning the pond was clear and the stocking was full of green mess, A ++++++ mate really does work.

My wife does this! It works.

probably using high 2x 30 w UV will help to solve the issue . my pond is 12x4x2.5 ( depth ) feet it works water clean but cant stop those that are sticking on the wall

Hi All Some answers to questions and replies to other comments. The pump size is 2500 litres / I do Have UV 25 watt lamp in filter box / I do have air pump running. For those who seem so question if it works ?? It is a fairly cheap set up , small cheap 2500 pump/some hose /and some 15 denim ankle length stocking. I have noticed that the stocking does collect much more on sunny days and hardly any after a few dull days. Someone also mention why not put it under water , the answer is that you can see when stocking needs changing and it is easy to do on my set up. Best regards Tony

You can see it turn green. I'm trying this. Tomorrow! 👍

Beautiful pond!

I gotta try this .. the green is driving me crazy. My husband wants to fill it in and plant flowers!

Thanks for the video going to try this for sure.

The advantage to a UV filter is that it kills pathogens. I was surprised too that a 10% water change kind of kicked my pond into gear this year. Your mileage may vary.

I try it , great results cheers

That's a pretty good idea man
