DIY home made cheap Biological Filter for your Koi or Goldfish Pond for under $100

Rod Ingersoll shows in detail how he designed and built a home made biological filter to accompany his new fish pond. Further information can be found at www.diykoipond.com.

The filter was designed to replicate a natural wetland type system and should allow for optimum fish and plant conditions. In this filter Rod creates an aerobic system that will breakdown fish waste (Ammonia) and convert it to nitrate for plants and will allow more fish to be kept in the pond. The bio filtration system after a few weeks will aid good bacteria to grow on the filter medium for great fish health. The system was built and tested thoroughly in about 3 hrs and should require very little maintenance at all. This Bio mechanical water filtration system is for Koi, fish ponds, and water gardens but could be just as easily applied to other situations. Its simple to setup & run. All up it cost approximately AU $100 to build.

I must say that i did get a great deal of knowledge from the following DIY koi fish pond ebooks and bonus downloads. They taught me loads of great tips and tricks i needed to help me along the way building and designing my pond and filter system. Im sure it will also help you too: www.diykoipond.com

I am going to build a koi pond and I think i'll use this design, I am going to put a bridge over it and the bridge would cover this up just fine!

The only difference is I think I'll use a solar panel to run it.

I subbed because of this video, now I'll watch you're others, thanks for the post!

@drydjinn100 Fantastic, i love hearing that i have helped others with there ponds.

Kapulfilms, what type of pump did you used? whats the GPH of that pump?

[Kapulfilms]

@betomty84 5000 lt per hour pump was used

I made it today but I need another overflow/outlet my pump is to fast and starts to over flow the trash can. Going back to home depot tomorrow. than you for all the help.

I am looking at filters and not sure what is a good one. I have an above ground pond stands about 2 1 /2 feet tall and the water level is about 1- 1/2 feet of that. so i need something that will pump up about the 3 feet and in to a canister just like yours. I like your design best for my set up. I am seeing this head rating I am guessing that pumping power. Pond has 2 red eared sliders and is about 150 gallons Quiet One Lifegard Fountain Pump 991 GPH or Lifegard Quiet One 4000 these to much?

good job

Also, im going to guess a settling tank is unneccessary for two goldfish whose body length is abut 3 and 3.5 inch roughly

Can your design be adapted into an undergravel filter type set up? Also how small could you make it? I have two goldfish in a 30ish gallon tank. what size powerhead would be recommended and the size of the filter bucket?
