My setup can give you an idea of how a homemade bio filter works and how to make one. Use my design or use part of it to make your own setup that works for you.
Trust me, this filter keeps my water crystal clear, you won’t regret making your own filter.

If you had your pump at the opposite end of your pond, it would circulate the water more efficiently. Nice job
How many watt pump is that?
Maybe you forgot to cut a hole under d trash bin for d DRAINAGE PIPE.
You can also tie the sponges so they dont come loise and float up
If you add another bulkhead at the bottom for a drain pipe then it’ll reduce your clean out time significantly. You can drain out the solids at the bottom periodically without removing everything.
Can't u just use a normal sponge for ur fitter???
Very impressive!!!
Is that a pool? Looks like a pool
Amazing !!
Nice 👍
Thanks for sharing. How often do you have to clean the filter? Reason for asking is I have to clean my filter every 2 weeks…
R u bad girl?
How often you need to clean the filter? Do you have a valve below to clear the feces once in a while?
Love your video at the end though, when testing you should use water that’s colored from a fish pond like the one you are showing but slightly filthy and show the difference with a glass of that filthy water and a glass of the water after filtration will be nice to see the difference, thank you
How many watts does your submersible have?
Thanks for sharing it my forever friend, i will do pond when going back to Philippines, Godwilling
What about using charcoal as a filter instead? Bio char
Great video! Thank you!!
How long would that last you before you replace the sponges and scrubs as filter?
All those plastic won't release microplastics into your water?
What is watt of puller water pump?
Which type pumps used for this and how many Watts pump used
I am going to make one filter based on this idea. Thanks a lot. By the way, this design have one small problem. If the pump switched of , all the water inside the bucket including the filtered waste will be pulled back to the Pond. You can avoid that problem by simply adding one airing point just before the water inlet to the bucket.
I made 2 of these following your amazing video! I’ve had then 18 months now and they have been impeccable, your video is amazing and I can’t thank you enough for this, god bless and thank you from England 🙏🤗
So nice I would swim in it when its warm 🙂
Thanks for the idea my son and I just made one for our turtle pond came out great and saved us a lot of money
How often do you change the bio balls ?
This is the best pond filter video I've ever seen. I feel like I finally understand how to make a biofilter! Thank you so much! We are putting in a swim pond next summer. How often do you have to clean out the filter?
Hey Bertha, your hand was blocking my view
I like it… sabskrip… ☺😍
works but looks like crap. why the h would anyone want this beast sitting on the wall of their pond. no thanks
Great job in building this swirl bio filter. May I suggest you place an air stone in the bio filter to promote good bacteria growth. Mine set up is similar but with a 5 gallon bucket.
Chola fish pond filter
I like your filter system, what pump are you using and does it consume a lot of electricity ?
