Rotary Drum Filter,RDF Fully Automatic Water Self-Cleaning Filtration，Efficient UV lamp， for Koi Pond,Fish Pond,Aquarium,Aquaculture

Wow. This thing is a workhorse. I’ve had it almost a year now. And my pond is definitely clearer than before I had it. It is ran on a 2400 gallon pond with two return barrels with plants in them. I just let the removed waste hit the ground.

The media could not be loaded. I have this version for 6 months - working with my 8000 gal pond. I have pre filtration, then to be drum after pre filtration. This removed and cleared water significantly. Even though it’s not on a timer clean, the float switch only works great. When first installed cycle often need to watch water level. After 6 months not so much.Seller needs to band the drum down to protect from shipping damage!. Handlers will tip to ship and drum screen beat to death…lucky not punched thru.

What's bad:1. Box was delivered crushed. The cardboard isn't nearly strong enough for shipping these filters. The filter seems to function ok though, miraculously..2. Filter is rated at 4000 gph, but I couldn't even get close to that. With my pond water about 3000gph was the best I could do, without the filter in a perpetual cleaning cycle. No idea where the 4000 came from.3. This filter is pressure input, gravity output. You need to match the filter output fitting, so free flow output matches pressure input. Most importantly, the water output can never rise above the top of the output fitting. That means this filter must be physically above all output destination fittings in order to function correctly.4. Input water quality greatly affects this filters performance. Leaves and twigs cause bad things to happen when they get inside the drum. Need to filter those out first. The cleaning cycles are supposed to wash the waste out the sewage port. But about 5 % of that waste, ends up splattered on the inside walls of the filter . This ends up right in the output water. So in my case, I still have to clean this filter monthly. This was not designed to be easy to clean!.5. 200 line screen is equivalent to a 74 micron filter. This works wonders for clearing the pond water of flotsam. But fish slime passes right through. So you end up with fish goop all over the inside of the filter, which then gives rise to worms, bacteria, which all happily move into the filter. It's really got to be cleaned regularly to function correctly.6. This is NOT fully automatic, set and forget. Did I mention you have to clean it too?!, and yes, it was not designed to be easy to clean. It's a pita in fact7. You have to adjust the flow rates in and out to minimize washing cycles. For my setup, the washing cycles waste about 35 gallons of water each day. This means your plumbing needs to support flow rate limiting, and you'll need to have a way to constantly replenish the water for your fish as it's lost due to filter cleaning.8. Maybe other brands would be easier to deal with, but this is the only one I've ever bought, so I have nothing to compare too. It works.9. Comes with no warranty, zero, nothing. Cross your fingers.The good:1. It actually works to clear the pond water.2. The cleaning cycle is a pleasure to behold!3. This thing dropped my labor from cleaning my filter sponges every 2 days, to cleaning a drum every 3 to 4 weeks. Saves me a lot of time. But it's not cheap, and it's not easy!4. You get about 35 gallons of free fish fertilizer every day, so pair this with a big garden, and watch your plants grow! By the way, fish fertilizer stinks, so prepare yourself!

Works flawlessly! Super easy to install and operate. Highly recommended.Update. Unit has been working flawlessly for three months. Wish I had gotten the largest one though.2nd update. This unit has been working non-stop for six months. I am running it through the winter since it is feeding my bakki shower and moving bed. No issues whatsoever this far.3rd update. It is been a year and the thingy still going strong. I converted it to WiFi enabled with a $20 bucks relay managed by Alexa.No way you can beat this little gizmo. Still feeding my bakki shower and two moving beds (75G/each).

Working fine. Need to do better on packaging, spray bar was broken.

Ok,A real review, not a Bot! I ordered 2 of the 8000 GPH "rate" ones with UV sterilizer. Got my first one, BUSTED and smashed.... my other one MIA. I returned the one I got because it was beyond fixing. Reordered and after some time got 2 that were better packed. I set them up without issue and the results are EXCELLENT!!! I use one on a Dwarf Caiman Pond (Crocodilians) and another on Large Alligator Snapping ponds. I use the drum filters to remove a fair bit of debris etc and also have Biological filtration included. I love how much material is caught by the drum and I backwash the drum screen back into the system but use a filter sock to separate the debris. This works well as there is no water loss and I can just change out my sock and save myself a fair bit of the hassle of clogging my Bio filters. Overall, I really like the products and have had for about 8 months and will buy more for other various needs. Worth the money in my eyes and I have a huge amount of experience with filtration, fish and animal management. I know when things suck and this is actually quite decent considering the price etc..Kevin - New England Reptile Distributors, Inc.

You are being scammed this unit is trash, very low build quality full of components that will rust in no time. Controller is in Chinese with 0 instructions or explanation of any of the settings, wiring is shoddy & barely even fits in the box. It’s not even CLOSE to being worth its asking price.You will NOT be able to use this as a regular RDF it’s a NO/NC that directly breaks out. So it will either float water but never rinse because second level goes down it breaks the rinse (stupid) or it does fully rinse but only if it float switch goes back down. Which also won’t work because as level rises it literally can’t go back down.So it can rotate a little or do nothing. Manual rinse works but not the point. No timer or interval mode to just make sure it rinses they want another $200 for a cheap controller still in Chinese.It’s highway robbery I will be returning this POS and just making my own RDF with a controller that’s actually in English and works.Totally useless don’t even bother either get a good one or just go fully cheap you are getting no benefit with this one it isn’t midrange it’s the cheapest lowest of the low with absolutely nothing to offer
