Thank you very much for your effort jeff. To clearly bring unexpected method to test static media as a mechanical filter. Yes, it bring clear water also 👍👍👍. Keep post good stuff. Regards from Indonesia

That sir, is a beautiful set up you have there.

Thank you for the best videos and the best explanation

You rock bro! Thanks for sharing your brilliant ideas!

3:55 you'll need a UV sterilizer to remove the free floating algae. That's the only way you can turn the green water clear. Remind you algae is not necessarily a bad thing and your koi fish will enjoy eating algae. The algae is helping to break down the nitrates and phosphates so technically it's healthier for your fish and your pond and the fish don't care either way if the water is clear, green, or brown as long as it's healthy.

I would love to see more of that underwater leaf trap and pump setup. Because of your videos I’m seriously considering a single barrel system for a 600 gallon pond I have.

AWESOME pond there & fish wish I had a place where I could have that size pond.

Wow!!! Water is crystal and fish look awesome!!!

Now that some very nice mature media 👌

Thats crazy how much muck thats taken out, great vid buddy 👍🐟⛩

Ok, you had me at hello. Now your just showing off. !!!!

Love the lilies

Incredible👍👍👍

Hi mate I would personally try putting more air to your moving bed as some of the k1 is not moving it needs to all be moving for best results.

Very interesting! Thanks for sharing!

I think you would be better of with the moving bed filter first in the series and I suspect that the packed bed filters work better. Do you have any ammonia in and out figures? What is the flowrate and filter volumes?

Why would you run two static and a fluidized if the fluidized is at least three times more efficient than the static if not more? Also can you show us how to recreate your filter system? The pond looks fantastic. Nevermind found it. Thanks!

Do you have a video on how you build your flowing filter? The last filter drum with moving water. I am in the middle of building my own filtration system with 3 barrels and would like to know how you had yours set up! Your videos are very helpful!

Do you have any videos of your full plumbing setup?

Hi Jeff - Love your videos. You have said that mechanical filtration through K1 media is most efficient at lower flow rates through the media which makes me wonder why you choose to run through the barrels in series. I am wondering if the first two drums would remove more dirt particles if your feed from the pond pump was split 50/50 using valves so that the flow rates would be cut in half through each drum. They both could then discharge into the same floating media drum. They would probably require a different cleaning frequency. I am about to build my own system and would value your feed back. Thanks, Les.

Hi Jeff are the plans free or do we have to pay for them. Just wondering if you had a step by step instruction. Thanks

K-1 is an excellent static media and almost no-one knows about that.

This k2 media looks awesome... much easier to clean than what I'm using.... how many cubic feet is needed per barrel?

Hi Jeff, nice video, who's instructions did you follow to build the 3 barrel's, and what are you moving the air with?

Is there a reason you add k1 to the first drum and would k2 be better throughout all three? I didn't know if k2 being smaller would plug up the media to quick in the first drum?

Hi @jeffakama what is the ratio of k1 you need. My reading indicates up to 25% of total volume. Is this correct?

How do you deal with string algae blooms in the spring? I inherited a koi pond and learning how to take care of it. This pond was not built very well. It only had a submerged filter box that constantly got clogged and had to be cleaned every 2-3 day in the summer. I decided to build a similar set up like yours but it's only a two-stage filter set up because of limited space (1. Static k1 main bed filter and 2. Moving bed k1 filter ). When the string algae started to die off it clogged my main bed filter pretty quickly and my k1 rose above the water. Also, how often should I be cleaning the main bed filter?

Hi again. So I did a rigorous clean of the K media in the drum just three days ago. I flush out the water from the drum. Then I used a tool like a shovel and stir the K media while it was still flushing out. I did that until water is all flushed out. Then refilled it with new water inside the drum. I’ve flushed out the water a couple of time already in past three months. But never actually stir and mix and clean the media until this time around. Now it’s been three days I noticed the water is black and grey. Not algae looking at all. Any advice? Thank you so much. I really hope you can help. Cause I was so pleased with the result from the first three months but now this. Thanks again.

Sir, you have got a nice setup. I have a few questions & one suggestion to offer. Question no 1: In the 1st & 2nd barrel have u used the bigger size MMBR media, like the ones used in the large waste water treatment plants? I have used the industry standard MMBR in one of my Aquarium tank to make an internal Sump. Question 2: Which pump are you using to circulate the pond water. Suggestion: Sir, Instead of daily stirring up the barrel no 1 & 2 with a wooden stick, won't it be better if you add a powerful submersible pump at the bottom of each barrel & start it for sometime to completely stirrup the waste matter. You dint need to run the pump for long time. Or, just like buy one such powerful pump & can use it in both the barrels. Tie the pump to a heavy stick & can dip it into the barrel needed to be stirred up. Thanks for your time.

Where did you find that shower drain.? That is not available around me and I am a contractor. Please send link.

I have several 100gal stock tanks and was planning to use one as a bog filter for my 1000gal pond. After seeing your videos I’m thinking of the media instead. Your thoughts would be appreciated. Thanks!

Very interesting. How many percent of volume of your drum is the volume of the K1?

upflow or downflow direction of water in your barrel of kaldness?

great video. are you using 4 cubic meters per barrel or total between the three?

How much liters of k1 media per kilo of fish do you put

I have the same set up could you tell me how many cubic lbs you have total thanks

I wish I could get my K1 to sink and tumble. At least I am getting mechanical filtration from static.

How much K2 media do you use for your first static barrel?

Where did you get that huge filter sock?

Nice pond 👍🏻

Hai Jeff!!. What is the quantity of bio/ mechanical mbbr media you use for your pond? Is it depended on water quantity or fish stick density? Pl explain

Jeff, how many cubic feet total of K1 media are you using in that 3 barrel setup? Thanks!!

Where do you buy your K1?

You need stronger air pump for K1 media.

Is that all you've got running mate 3 k1 beds ?

Not what you expected, your expectations must have been quite low then.

So K1 media also removes Algae?

look like you have algae problem. filter alone is not enough. you should have a UV light to kill the algae.
