How to build DIY filter for Koi Fish Pond 

This is a great IF you want to recycle the sludge; makes fir excellent fertilizer. Dirty water comes in, heavier crap settles to the bottom as the water is diffused. For looking for more like a bio- filter. You could add anything from lava rocks ( harder to clean out filter), bio balls, or mesh. The key is to provide a surface for " bio" to grow on. Still, you'll likely end up with sludge on the bottom, but the water will be cleaner from a " bio" point of view. Nitrates are is a factor that bio also addresses fairly well depending on the set- up. Adding a single UV light where the water pools before returning really makes a huge difference if you like clear water. Adding salt is another plus. Speaking experience 35x17x4deep pond with over 40 koi.

Great idea for this DYI pond filter. Well done I really like the Concept

Cool idea love fish 🐟

Много Добре!

A great video I really enjoyed it you have a new subscriber. I am original from Nottingham England but I emigrated to Newfoundland Canada in 1990 - 2018 I decided to keep koi in my garden pond like I did in the UK but here the winter is brutal like -20 is very common so we have our own chalenges. Plus we can’t purchase equipment so I have to make everything ie filters etc. Cheers Mate.

Quite creative. What of the aerator for oxygenation to make it a complete recirculatory system flow.

Ty for making the video

some friend suggested me that he burned a iron pipe piece or gi pipe in wood fire and then melted holes in the plastic drum.

Hi , what size pvc pipe fr inflow , outflow and drain?

did you forget to put sand and gravel and stones bruh ? filtration is incomplete without these at least for a dirty pond water!

Needs a drain in bottom

Just a sponge is enough ?? What about other mediums like bioballs, stones and another layers ??
