4500 GPH pump did not work as I originally planed.
So switching to JEBAO DCT 12000: 3170 GPH pump works well for this system

Most plumbing fittings and pipes are ABS as ABS costs less than PVC.

Nice build. The shop vac idea is a great one. Do you find the 2 inch increments for the base give adequate differential for the flow rate you need?

@PTranProductions 3 года назад

Thanks mate! Yes, with the 2x4 wood frame, it gave me a minimum 3.5” rise at every level which is adequate for the flow so far with a 3170 GPH pump.

@richardjohnson9566 2 года назад

I have seen many setups like this and yours is right up there with the best of them, especially the shop vac back wash method which I utilize in my larger system as well. I'm no expert all though I have been building ponds for my personal use as well as ponds for paying customers for over 25 years. I have made many mistakes and use these fourms to better my skills as a builder and koi keeper. I read through the comments and if I missed it, pardon me, but I don't know what brand of uv light you are using, but all that I have ever used have said to put your uv "after" the filter. You want the water to be as clean as possible before it passes through the uv, and at the rate of flow the manufacturer recommends, which I see you did with the piping and valves. Having the water pass through the filtration system first helps get out the larger particles of algae and other unwanted material that the uv filter can kill better, if the particles are smaller. Also, in all of the instructions and I've seen say to put the uv after the filtration and as low as possible to the last filter with the inlet and outlet facing up, as you have. There are numerous articles on this subject, but maybe your manufacturer recommends installing your uv before filtration. Bottom line, what works best for you and your pond , and by no means am I criticizing your application, only a suggestion. Great job on the filter!

@PTranProductions 2 года назад

Thanks Richard for your comment! Yes, I have done some research and initially I had the UV sterilizer after the filter which only makes sense for clean water to pass through the UV. However when I got my Jebao UV sterilizer and read the the instructions which stating that the UV sterilizer needs to be connected where the water pumped through and not gravity fed. So that’s how I ended up with my configuration today. I have not opened up the UV light housing to check but I guess there would be some kind of buildups inside. I may open it up at the end of this season to inspect and clean the inside when I close up my pond this year.

@richardjohnson9566 2 года назад

@@PTranProductions Understandable now with your setup being gravity fed. I used 55 gallon drums and had a Vortex pre- filter before my first barrel and was using 3" pvc throughout the system, which greatly increased my flow, so my uv could go after the filtration. That's one of the problems a person encounters with gravity flow, is getting the flow rate one desires after filtration. I do personally prefer a closed pressure system, but they are very expensive and have their own set of problems, especially getting the proper backwash, and taking pieces apart for maintenance. As I said in my original comment, what ever works best for you and your pond/fish. Happy ponding!!

@PTranProductions 2 года назад

@@richardjohnson9566 Thank you!

@ces69 10 месяцев назад

Where you mount your UV, either before or after your filter system depends on if you are running a pump or gravity fed system. If gravity fed it would go after the filters in the line that is being pumped back to the pond, if pump fed it would go in the pumped line feeding the filters! This is because the UV units construction is too small and restricted to allow a high enough flow of water through it by gravity, requiring the water to be pushed through under pressure of a pump!

@@PTranProductionsWhy are you shutting it down every winter? Reduce the flow if you want with a variable pump or ball valve but don’t shut it down. Filters take around 6-8 weeks to develop enough bacteria to “START” completing the nitrogen cycle but take years of continuous running to develop fully and plastic media is notoriously slow to develop a bacterial coating, even with the addition of live bacteria! Your filter is just getting established each year when you shut it down….madness!

No idea! It depends on your pump flow rate and size of your barrels. It is a trial and error thing.

When it is convenient and affordable, change all of that flex hose going through your UV to PVC pipe. With the flex hose you will eventually have a blowout. I have experienced this many times and had to change everything over to PVC

Thanks for the tip! This flexible kink-free PVC hose give me the flexibility to easily disconnect the UV light housing and store it inside the house for the Winter months. This flexible kink-free hose has a thick wall and heavy duty. So hopefully it won’t blowout easily. I did purchase one flexible hose from Amazon which was very cheap thin wall. So I returned it.

What made you choose K1 for you first barrel and not K2 or K3? I know you want K1 for the 3rd moving barrel. I just figure you would use K2 or K3 for the 1st barrel and K2 for 2nd, and K1 for 3rd moving barrel.

@PTranProductions Год назад

K1 has 4 spokes and K2 has 5 spokes which would collect/filter more fine sediment than K1 (as my understanding). That’s why K1 used as first stage (barrel 1) to filter larger debris/sediments then anything passing through will then be filtered by stage 2 (barrel 2 with K2 media) with any finer sediments. I didn’t want to use K2/K3 in the first barrel because I didn’t want it clogged up too quickly. K3 was not available in Canada or US that I could find at the time. K2 was only available on eBay through a California based seller. I could have used K2 or K3 for my moving bed because they have more spokes - more surface areas for beneficial bacteria to hang on but it’s all came down to availability and cost.

@leesilas Год назад

@@PTranProductions it is my understanding that it has nothing to do with the spokes as it does with the size. K1 per cubic ft will have more surface area then K2 even though K2 has more spokes, your can fit more smaller pieces of K1 in a cubic ft, then K2. That is why they say have your moving bed using K1 in barrel 3. I just figure you are trying to just collect larger debris in the first Barrel so you would want a larger media such as K2 or K3. But I understand it comes down to price and availability.

@PTranProductions Год назад

@leesilas I’ve never seen K3 so not sure about the size. However, K1 & K2 are identical in size/diameter. The only difference is, as I mentioned before, K1 has 4 spokes and K2 has 5 spokes. So ideally, 1 CF of K1 should be equal to 1 CF of K2 in term of quantity

@@NeotropicalFauna Yes, in my understanding, filter socks retain more particles, get clogged up faster and would be a pain to clean out. Yes, in terms of mechanical filtration, filter socks may be more effective than Kaldness but I am not sure if they’re efficient over all. With two barrels of Kaldness used as two-stage mechanical filter, this system has proven very effective and efficient overall in term of filtering, cleaning and maintaining. Clear pond water can still be achieved within a week after start up and maintained clear thru out the season. You could leave the Kaldness alone running for up to 4 weeks without cleaning - this is good if you’re away on a vacation. Watch my various update videos on this system to see for yourself. So If you don’t mind to clean out filter socks every other day, go with filter socks If you want to enjoy your clear pond water more and do less work then Kaldness is the choice. Economically speaking, filter socks may be cheaper than Kaldness, so whatever works for you. My most expensive spending on this system was the K1 & K2 media.

@PTranProductions 3 года назад

Thanks for your suggestion Garry Stedman! I guess you meant ‘turned the UV flow down’ as to restrict/reduce the flow of the water to the barrels. This way would work but then the pump wouldn’t run at full capacity and will have to work harder thru restricted flow. Anyway I had the Jebao 3170 GPH which was not strong enough for my skimmer so I might as well use it for the 3-barrel filter.

@leesilas Год назад

The flow through your UV light should be slower to give the light time to kill the algae and bacteria. One guy I know put two 36 inch UV lights in a row so the water flowing through has time exposed to the UV long enough to kill it. What I did on my pond is put in a small pump that just goes to the UV abd back to the pond and it made a HUGE difference. I live in Florida USA, and algea grows fast in the summer, but now with this set up it does not.
